## Additional Social Work Flashcards

Term
 Nondirectional
Definition
 There is a relationship between variables but the direction of the relationship isn't stated.
Term
 Empirical
Definition
 Is evidenced by research. Is observable, not base on faith. You can observe what happening.
Term
 Observation
Definition
 Is a type of correlational (i.e., non-experimental)research in which a researcher observes ongoing behavior. You believe what you can see.
Term
 Internal Evaluator
Definition
 A program evaluator that is in house, is affiliated with the organization for which the evaluation is being completed.
Term
 External Evaluator
Definition
 A program evaluator that is from outside the organization for which the evaluation is being completed. This type of evaluator is typically hired.
Term
 Hypothesis
Definition
 A theory based prediction of the expected results of a the relationship between variables in a research study. It forms the research question. The difference between this and a research question the study directions. This is always a statement, not a question.
Term
 Variable
Definition
 This is found in every experiment. The types are : dependent, independent, and controlled. Furniture is an example of this, but table is not. It’s always a category and it varies. Age is an example of this, but being 37 is not.
Term
 Probability Sampling
Definition
 It's a method of sampling that utilizes some form of random selection. In order to have a random selection method, you must set up some process or procedure that assures that the different units in your population have equal probabilities of being chosen or and equal chance of being selected. Random and stratified stratified are examples of this.
Term
 Random Sampling
Definition
 A type of probability sampling. A subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple sample that is meant to be an unbiased representation of a group.
Term
 Stratified Random Sampling
Definition
 This is a population sample that requires the population to be divided into smaller groups. Random samples can be taken from each of the smaller groups. Ie: social workers: Statistically 85% are female, so then you would randomly select 85 females from a listed of social workers to obtain this sample.
Term
 Non-probability Sampling
Definition
 A type of sampling in which all of the persons, events, or objects in the sampling frame have an unknown, and usually different, probability of being included in a sample. Types are: purposeful, convenient, snowball, quota, available.
Term
 Purposeful
Definition
 This type of non-probability sampling looks for participants who fit criteria. The participants are purposely selected for inclusion in a research sample,
Term
 Convenient
Definition
 A type of non-probability sampling that relies on the closest and most available research participants. It typically includes a dual relationship (ie: teacher recruiting their students as participants).
Term
 Snowball
Definition
 A type of non-probability sampling in which one participant leads to another.
Term
 Quota
Definition
 This is a non-probability sampling technique wherein the assembled sample has the same proportions of individuals as the entire population with respect to known characteristics, traits or focused phenomenon (ie: for a project we might need so many a specific number of females, hispanics, people in their 20's, etc to match the typical population).
Term
 Available
Definition
 A non-probability sampling procedure that relies on the closest and most available research participants (ie: going to the mall and finding whoever is available).
Term
 Logic Models
Definition
 This is a tool used by funders, managers, and evaluators of programs to evaluate the effectiveness of a program. They are usually a graphical depiction of the logical relationships between the resources, activities, outputs and outcomes of a program.
Term
 Theory
Definition
 This explains the topic and is bigger than hypothesis. It's and explanation of how something works. It is not necessarily the truth.
Term
 Baseline
Definition
 This method of data collection is the starting point, the pretest, the measurement you took at the beginning, where you started.
Term
 Benchmark
Definition
 This represents what we’re shooting for, the target or goal, a specific score. It's an acceptable level of success or competence.
Term
 Process Measures
Definition
 This is a form of measurement like a survey, an interview, a test, classroom evaluations. It helps improve the process.
Term
 Outcome Measures
Definition
 This can be an assessment or test and tends to have a score related to it. It's the end result such as your final grade. It measures the entire outcome results.
Term
 Treatment Group
Definition
 Represented by ROXO. This group receives a random assignment and the treatment or intervention (ie: in a student/flashcard experiment, this group would be randomly assigned to use flashcards)
Term
 Control Group
Definition
 Is represented by RO_O This group doesn’t receive the treatment or intervention. (ie: in a student/flashcard experiemtn, this group would not use flashcards)
Term
 Sampling Error
Definition
 An understanding that there are different averages because of natural variances in a population. It's the tendency for each sample to have its own natural occurrence of error, slightly different to the whole.
Term
 Sampling size effects on sampling error.
Definition
 Understand that the bigger the sample, the closer you are to your true mean or true average and the less likelihood of sampling error; the smaller the sample, the larger the sampling error.
Term
 Nominal
Definition
 This is a level of measurement that uses labels. It is the most basic, the lowest measurement level you can use, from a statistical point of view. It classifies variables by assigning names or categories that are mutually exclusive without order. (ie: color, furniture, or YES/NO scale)
Term
 Ordinal
Definition
 This level of measurement puts items in order or satisfaction. (ie: rating items from high to low or most to least, you can put them in order)
Term
 Interval
Definition
 This level of measurement is quantitative and measurable. It has a zero point but not absolute zero point, such as temperature.
Term
 Ratio
Definition
 This level of measurement is the top level of measurement, has a true zero point.The simplest example of this is the measurement of length or weight.
Term
 Indicators
Definition
 This is a part of operational definition. You can say yes or no to it. Putting this into groups creates a dimension.
