Term
Errors in Reasoning
Definition
Types are Selective Observation, Illogical Reasoning, Inaccurate Observation, Overgeneralization, Resistance to Change
Term
Overgeneralization (Errors in Reasoning )
Definition
To infer from few particular facts, statistics and the like beyond an appropriate or justified limit. i.e. only the poor commit crime.
Term
Selective Observation (Errors in Reasoning)
Definition
look at things according to personal beliefs, regardless of fact.
Term
Inaccurate Observation (Errors in Reasoning)
Definition
Errors that occur often in casual conversation and in every day observation.
Term
Illogical Reasoning (Errors in Reasoning)
Definition
prematurely jump to conclusions or argue on the basis of invalid assumptions.
Term
Resistance to Change (Errors in Reasoning)
Definition
the reluctance to change our ideas in light of new information. --> Excessive devotion to tradition --> Uncritical agreement with authority
Term
What makes criminal justice research scientific?
Definition
Uses the scientific method. Avoids basing conclusins on our emotional reactions to people and events. Allowing our observations to conform to what we see and not to our needs. Not allowing our perceptions to be distorted by traditional beliefs about social phenomena. Crtitically evaluate what authority figures tell us to be true.
Term
Motivations for Criminological Research
Definition
1) To create policy. 2) Find out if a policy will work or not. 3) Find the truth for interest a.k.a. academic motivation, or 4) personal interests or motivations.
Term
Types of Research
Definition
Descriptive, Exploratory, Explanatory, Evaluatory
Term
Descriptive Research
Definition
Quantitative research attempting to define or describe social phenomena. The "who? what? where? when? why? and how many? questions to be answered.
Term
Exploratory Research
Definition
Qualitative research to see how people get along in specific settings (i.e., gangs, prisons) and situations (i.e. drug addicts). Meanings behind people's actions, see what issues concerns people. Answers the question: "What is going on?"
Term
Explanatory Research
Definition
Identify cause and effect behind phenomena. Answers the question: "Why is this going on?" i.e., Why do juveniles become delinquent? Helps us predict how one phenomenon will change or vary in response to variation in another phenomenon. i.e., If unemployment increases, will crime increase?
Term
Evaluatory Research
Definition
Takes the cause and effect explanation to determine the effect of social programs or other types of intervention. Considers the implementation and outcomes of social policies. Answers the question: "Will this policy work?" and "How does the policy work?"
Term
Strengths and Limitations of Social Research
Definition
Research problems tend to be too focus and be limited in scope. Research does however help us to be specific.
Term
Types of Research Methods
Definition
Quantitative Methods, Qualitative Methods
Term
Quantitative Methods of Research
Definition
The method involving the counting of data and the analysis of this data using statistics
Term
Qualitative Methods of Research
Definition
The method involving the usage of written or spoken accounts, typically not involving the counting of data statistically.
Term
Validity
Definition
Statements about reality or perceptions are correct (it is the major focus of all studies, regardless of method or philosophy)
Term
Measurement Validity
Definition
exists when a measure measures what we think it measures
Term
Causal Validity
Definition
exists when a conclusion that A leads to/results in the correctness of B.
Term
Evaluating research questions
Definition
Three factors are feasibility, social importance, scientific relevance
Term
Feasibility (Evaluating Research Questions)
Definition
Consider if the theory is difficult to perform, such as too much time or too expensive.
Term
Social Importance (Evaluating Research Questions)
Definition
Consider if the theory matters in society. Do we care about this?
Term
Scientific relevance (Evaluating Research Questions)
Definition
Consider if there is prior research done. Is the research filling the gaps of existing research?
Term
Role of Criminological Theory
Definition
To study why individuals commit crimes and why they behave in certain situations. By understanding why a person commits a crime, one can develop ways to control crime or rehabilitate the criminal.
Term
Research Hypothesis
Definition
states a relationship between two or more variables
Term
null hypothesis
Definition
states no relationship between two or more variables
Term
Independent Variable
Definition
The cause. The variable that creates change or causes variation to another variable.
Term
Dependant Variable
Definition
The effect.The phenomenon you want to explain. A variable hypothesized to vary depending on or under the influence of another variable. It depends on the independant variable.
Term
Deductive Research
Definition
Research using reasoning that works from the more general to the more specific. Sometimes this is informally called a "top down" approach. Conclusions follows logically from premises (available facts)
Term
Inductive Research
Definition
Research using reasoning that works from specific observations to broader generalizations and theories. Informally, we sometimes call this a "bottom up" approach. Conclusion is likely based on premises. Involves a degree of uncertainty.
Term
Why do we need to consider research ethics?
Definition
In order to protect human subjects from unethical and harmful research.
Term
Belmont Report, 1979
Definition
In response to the Tuskegee syphallis report, where black men was purposely injected with syphallis, created the standard for ethical research by guidelines and regulations.
Term
Respect for persons (Belmont Guidelines)
Definition
Treat persons as autonomous agents and protect those with diminished autonomy (elderly, children, mentally disabled, prisoners)
Term
Beneficience (Belmont Guidelines)
Definition
Minimize possible harm and maximize benefits
Term
Justice (Belmont Guidelines)
Definition
Distributing benefits and risks of research fairly.
Term
truthful and valid results (Ethical Principles in Research)
Definition
Research serves no purpose if it is not obtained. Must be as objective as possible without bias. Research that seeks to validate our own prejudices is not valid or ethical.
Term
honesty and transparency regarding research procedures (Ethical Principles in Research)
Definition
Researchers who publically and honestly report their research methods are less vulnerable to political or personal pressure to distort the result of their study. Publication is vital to the concern as it allows others through the peer review process to evaluate the appropriateness of research methods.
Term
Protect research participants (Ethical Principles in Research)
Definition
Voluntary participation , guaranteed anonymity and/or confidentiality, and research that benefits the subjects more than the foreseeable risks are ways to ensure this.
Term
Voluntary participation (Protect research participants, Ethical Principles in Research)
Definition
Subjects who participate without coercion, with information given about the study, and an informed consent from any autonomous person (.
Term
Avoid harming research participants (Ethical Principles in Research)
Definition
Ensure that subjects are free from physical or psychological harm. If there is harm, ensure that there were measures implemented to reduce or address potential harm.
Term
Criteria for obtaining informed consent (Protect research participants, Ethical Principles in Research)
Definition
18 years old, not in prison, or mentally disabled) and written consent forms at a 5th-8th grade reading level
Term
Avoid deception and misleading research subjects (Ethical Principles in Research)
Definition
Should be avoided except in limited circumstances. One should always analyze the potential harm when applying to a subject.
Term
Maintain privacy and Confidentiality (Ethical Principles in Research)
Definition
Ensure that the subjects identity is unknown or known but not revealed in the study. If the study involves a situation where there is no expectation of privacy, then it is okay to not be confidential.
Term
Ethical use of research (Ethical Principles in Research)
Definition
Considering the ethical dilemmas, one should be mindful of how studies are used to create programs or policies. Protect yourself from future usage or misusage. i.e. Minneapolis Domestic Violence study that created policies for mandatory arrests for domestic violence disputes because people only depended on that one study.
Term
Empirical correlation (Criteria for Causation)
Definition
Must show that variables are related through observable evidence that isn't assumed. Must show that changes in IV effects the changes in DV. Must vary together. Must be stated in the hypothesis.
Term
nonspuriousness (Criteria for Causation)
Definition
Just because there is a relation doesn't mean one variable caused the other, due to a third variable that appears to also have a direct connection. Must be sure there isn't a third variable.
Term
time order (Criteria for Causation)
Definition
Must be sure that changes in the IV occur before changes in the DV. Often difficult to establish cause to effect relationship in social research because it can be difficult to determine which came first.
Term
context (Criteria for Causation)
Definition
Set of circumstances surrounding an event or situation. No cause has its effect apart from some larger context involving other variables (when, for whom, and in what conditions does that effect occur?). Cause is really one among a set of interrelated factors required for the effect.
Term
causal mechanism (Criteria for Causation)
Definition
Process creates connection between variation in an independant variable and the variation in the dependant variable it is hypothesized to cause. The reason why the relationship is causal.
Term
Experimental Research Design
Definition
True Experiments, Have 3 features that help establish criteria. 1) two groups (control and experiment group, 2) Random assignment of groups, 3) Pretest and Post-test
Term
Two Groups (Criteria for Experimental Design)
Definition
Must have a Control and Experiment Group
Term
Random Assignment of Groups (Criteria for Experimental Design)
Definition
Each subject must have an equal chance of getting in to the group.
Term
Pretest and Post-Test (Criteria for Experiment Design)
Definition
Assessment of change in the DV in both groups after the experimental group receives the experimental condition.
Term
Quasi-experimental Research Design
Definition
Resembles experimental design, but not quite all the features. Do not use random assignments, so has less explanatory power and more validity problems.
Term
Nonequivalent Control Group (Quasi-experimental Design)
Definition
Similar to experimental design, except the subjects in the groups are not selected randomly. Groups are named comparison (control) and the treatment (experiment) groups. A lot more doable due to being more selective, not forced in to groups, and no due process problems.
Term
Individual Matching (Nonequivalent Control Group)
Definition
Selecting groups based on individualizing characteristics of each subject in the group.
Term
Aggregate Matching (Nonequivalent Control Group)
Definition
Involves the average characteristics of a total group or in similar groups.
Term
Before and After (Quasi-Experimental Design)
Definition
No comparison group, only one group is observed. All members in the group receives the treatment or intervention (i.e. a new law passing). This is the weakest type of design because it can not draw conclusions about effectiveness of treatment from the result.
Term
Ex post facto control Group (Quasi-experimental Design
Definition
Study done after the fact, through retrospectively looking back. Could be the same as non equivalent. Identifies treatment and comparison after the results have already occured.
Term
Time designs
Definition
How long or often the studies are done. Studies can be done as a cross-sectional study or a longitundinal study.
Term
Cross-sectional (Time Design)
Definition
A snapshot at a period of time. Can not determine causal order, but sometimes can infer if the timing information exists.
Term
Longitudinal-Repeated Cross Sectional or Trend Study (Time Design)
Definition
Data collected at 2 or more points in time from different samples selected from the same population. i.e., surveys on public opinion
Term
Fixed sample panel (Time Design)
Definition
Study on the same group of people at several intervals, looking at change in the individuals. i.e., Following the same group of offenders after they are released from prison to learn about reentry.
Term
Difficulties with the Fixed Sample Panel (Time Design)
Definition
Expenses (i.e. incentives, difficult to track subjects), Attrition (i.e. quitting, disappearing, death), Subject Fatigue (i.e. subjects tired of answering the same questions)
Term
Event Based or Cohort Study (Time Design)
Definition
Group of individual units who enter or leave defined population during a specified time period. i.e., 2012 middle school students who start drug use at the same time., comparing like with like based on time or age.
Term
Cohort (Event Based or Cohort Study)
Definition
Subjects who experience a similar event or have a common starting point.
Term
Internal Validity of Research Designs
Definition
Only regards the Independant variable effect the dependant variable. Conclusions reflect what actually occured in the experiment. The ability to yield valid conclusions is determined by comparibility of experimental and control groups.
Term
External Validity of Research Designs
Definition
the validity of generalized (causal) inferences in scientific experiments as experimental validity. In other words, it is the extent to which the results of a study can be generalized to other situations and to other people.
Term
Threats to validity in research designs
Definition
o Selection bias, Endogenous change, External events, Contamination, Treatment misidentification
Term
Selection Bias (Threats to Validity)
Definition
Before the experiment or treatment, there is a difference in group to begin with.
Term
Endogenous Change (Threats to Validity)
Definition
Subjects might know what to expect, may learn or grow wiser. Could apply to fixed sample panel designs.
Term
External events (Threats to Validity)
Definition
Something catastrophic happens where life circumstances change that affects the study. Major events that no one has control over.
Term
Contamination (Threats to Validity)
Definition
Crossover of some treatment group subjects in to the control group.
Term
Treatment misidentification (Threats to validity)
Definition
Mislabelling of outcomes. i.e., Hawthorn effect, where people change how they acted because they are being watched.
Term
Population
Definition
The entire group you want to generalize your research to. (i.e., individuals or other entities like cities, states, prisons, schools, etc.)
Term
Sample
Definition
Actual people or unit of analysis we pick. A subset of elements/units of analysis from the population.
Term
Sampling frame
Definition
List of members of the population from which the sample is selected, as a way to narrow down the population. Selections can be filtered by time, place, number of institutions, etc.
Term
Units of analysis or Sampling Unit
Definition
Who or what (entity) you want to learn about.
Term
Unit of Observation
Definition
Where the data is collected from. Who or what must be observed to enable the researcher to study the entity of interest.
Term
Generalizability
Definition
the extension of research findings and conclusions from a study conducted on a sample population to the population at large.
Term
Sample generalizability
Definition
Ability to generalize from a sample of a larger population to that population itself.
Term
Cross-Population Generalizability
Definition
Ability to generalize from findings about one group, population, or setting to other groups, populations, or settings.
Term
Representative sample
Definition
A sample that is similar to characteristics of the populations it was drawn from.
Term
Non Representative Sample
Definition
May have characteristics that is over or under represented.
Term
Sampling Error
Definition
The difference between the characters of a sample and the population from which it was drawn. It is a numerical equation, where the larger the error, the less generalizable.
Term
Probability Sampling
Definition
Chance of selecting a specific sampling units is known and each sampling unit has a chance of being selected for the study. Allows us to know how likely it is that any element of a population will be selected for the sample. Allows us to select participants to be statistically representative of the population that one wants to learn about.
Term
Simple Random Sampling (Probability Sampling)
Definition
Identifies cases strictly on the basis of chance. i.e., flipping a coin or rolling a dice. Every element has an equal and independant chance of being selected.
Term
Systematic Random Sampling (Probability Sampling)
Definition
Determine the number of elements to sample in the population, but still has equal and independant chance. Selection can be done through sampling intervals.
Term
Sampling Intervals (Systematic Random Sampling)
Definition
Selecting the 1st element randomly from an organized listing and then selecting every nth element.
Term
Stratified Random Sampling (Probability Sampling)
Definition
Separate in to groups on categories which allows more control and increases representativness. Purpose to ensure that various groups will be included in the sample, especially the inclusion of small groups.
Term
Stratified Proportionate Sampling (Probability Sampling)
Definition
By creating a sampling strata based on a characteristic of interest. Randomly select cases from each stratum, in exactly the same proportions. i.e., Percentage in each group in the sample will be the same as the percentage in the population.
Term
Stratified Disproportionate Sampling (Probability Sampling)
Definition
The proportion of each stratum that is included in the sample in intentionally varied from what is is in the population. i.e., the percentage from each group in the sample will be different from the population. or selecting an equal proportion from each ethnic group to prevent underrepresentation. Common in qualitative research.
Term
Cluster Sampling (Probability Sampling)
Definition
Naturally occurring, mixed group of elements of the population. Each element appears in one and only one group at one time. i.e., Prisons as naturally occuring groups for sampling inmates or city blocks for sampling residents. Useful when sampling frame is not available or too expensive to cover.
Term
Nonprobability Sampling
Definition
Each member of the population has an unequal probability of selection. Typically used when one can't obtain a probability sample, a topic or study is inappropriate for probability sampling, such as vauge and uncertain populations, or as an exploratory study where there isn't a sampling frame, just to find out a group.
Term
Availability (Nonprobability Sampling)
Definition
Subjects are in the study because it is easy to find. i.e., Interviews at a mall, street corner, magazine survey, etc. Convenient, but possible bias and not representative of the population.
Term
Quota (Nonprobability Sampling)
Definition
It ensures characteristics represented in the sample reflects the population. Helps to get a more representative sample. May be representative of the particular characteristics for which they has been set, but may not be representative in terms of any other characteristics.
Term
Purposive (Nonprobability Sampling)
Definition
Each sample element is selected for a purpose or unique position of the sample elements. May involve studying entire populations of some limited group. A subset of a population, i.e., prison unit managers.
Term
Key Informant Survey (Purposive Sampling)
Definition
A target who can give knowledge about issues under investigation.
Term
Snowball (Nonprobability Sampling)
Definition
To approach one subject in order to find more referred samples. Useful in hard to reach population that have no sampling frame, but members know each other in the group or are interconnected. i.e., Drug dealers are interconnected, but hard to reach, rely on one subject as a source to others as a sample.
