Cards

Term
theoretical
Definition
concerned with developing, exploring or testing the theories or ideas that social researchers have about how the world operates.
Term
empirical
Definition
based on observations and measurements of reality -- on what we perceive of the world around us
Term
nomothetic
Definition
laws or rules that pertain to the general case
Term
idiographic
Definition
laws or rules that relate to individuals
Term
causal
Definition
most social research is interested (at some point) in looking at cause-effect relationships. -- ones that tell us how our causes (e.g., programs, treatments) affect the outcomes of interest.
Term
3 basic types of research questions
Definition
descriptive, relational (looks at relationship between two or more variables), causal
Term
cross-sectional study
Definition
one that takes place at a single point in time. In effect, we are taking a 'slice' or cross-section of whatever it is we're observing or measuring. snapshot
Term
longitudinal study
Definition
is one that takes place over time -- we have at least two (and often more) waves of measurement in a longitudinal design
Term
time series
Definition
many waves of measurement over time
Term
correlational relationship between variables
Definition
A correlational relationship simply says that two things perform in a synchronized manner.But knowing that two variables are correlated does not tell us whether one causes the other. Can't assume that just because there is a correlation there is a causal relationship - or that one variable causes another.
Term
third variable problem (spurious relationship)
Definition
it may be that there is a third variable that is causing the correlation we observe.
Term
types of relationships: positive relationship
Definition
In a positive relationship, high values on one variable are associated with high values on the other and low values on one are associated with low values on the other.
Term
types of relationships: negative relationship
Definition
Implies that high values on one variable are associated with low values on the other. This is also sometimes termed an inverse relationship.
Term
attribute
Definition
a specific value on a variable. For instance, the variable sex or gender has two attributes: male and female. Or, the variable agreement might be defined as having five attributes:

* 1 = strongly disagree
* 2 = disagree
* 3 = neutral
* 4 = agree
* 5 = strongly agree
Term
independent
Definition
the independent variable is what you (or nature) manipulates -- a treatment or program or cause.
Term
dependent
Definition
dependent variable is what is affected by the independent variable -- your effects or outcomes
Term
hypothesis
Definition
a specific statement of prediction
Term
qualitative and quantitative
Definition
All quantitative data is based upon qualitative judgments;and all qualitative data can be described and manipulated numerically.
Term
unit of analysis
Definition
The unit of analysis is the major entity that you are analyzing in your study. For instance, any of the following could be a unit of analysis in a study:

* individuals
* groups
* artifacts (books, photos, newspapers)
* geographical units (town, census tract, state)
* social interactions (dyadic relations, divorces, arrests)
--it is the analysis you do in your study that determines what the unit is
Term
ecological fallacy
Definition
occurs when you make conclusions about individuals based only on analyses of group data.
Term
exception fallacy
Definition
It occurs when you reach a group conclusion on the basis of exceptional cases.
Term
Deduction
Definition
Deductive reasoning works from the more general to the more specific. Theory, hypothesis, observation, confirmation
Term
Inductive
Definition
Inductive reasoning works the other way, moving from specific observations to broader generalizations and theories. Observation, pattern, tentative hypothesis, theory
Term
Positivism
Definition
rejection of metaphysics --t is a position that holds that the goal of knowledge is simply to describe the phenomena that we experience. The purpose of science is simply to stick to what we can observe and measure.
Term
post-positivism
Definition
post-positivism is a wholesale rejection of the central tenets of positivism. A post-positivist might begin by recognizing that the way scientists think and work and the way we think in our everyday life are not distinctly different. Scientific reasoning and common sense reasoning are essentially the same process.
Term
subjectivist
Definition
no external reality
Term
critical realism
Definition
A critical realist believes that there is a reality independent of our thinking about it that science can study.
Term
constructivists
Definition
believe that we each construct our view of the world based on our perceptions of it. Because perception and observation is fallible, our constructions must be imperfect.
Term
4 validity types
Definition
conclusion, internal, external, construct
Term
Conclusion validity
Definition
In this study, is there a relationship between the two variables?
Term
Internal Validity
Definition
Assuming that there is a relationship in this study, is the relationship a causal one?
Term
Construct Validity
Definition
Assuming that there is a causal relationship in this study, can we claim that the program reflected well our construct of the program and that our measure reflected well our idea of the construct of the measure? In simpler terms, did we implement the program we intended to implement and did we measure the outcome we wanted to measure?
Term
External Validity
Definition
Assuming that there is a causal relationship in this study between the constructs of the cause and the effect, can we generalize this effect to other persons, places or times?
Term
threats to validity
Definition
sample size is too small, measure of variable unreliable, heterogeneity, etc...
Term
informed consent
Definition
prospective research participants must be fully informed about the procedures and risks involved in research and must give their consent to participate
Term
risk of harm
Definition
Harm can be defined as both physical and psychological.
Term
confidentiality
Definition
assured that identifying information will not be made available to anyone who is not directly involved in the study.
Term
anonymity
Definition
the participant will remain anonymous throughout the study -- even to the researchers themselves.
Term
feasibility of a study...
Definition
how long the research will take, ethical constraints, needed cooperation, costs
Term
steps in concept mapping
Definition
preparation, generation of ideas, structuring, representation, interpretation, utilization
Term
threats to external validity
Definition
people, places, time
Term
improving external validity...
Definition
random sampling
Term
population
Definition
the group you wish to generalize
Term
sampling frame
Definition
The listing of the accessible population from which you'll draw your sample
Term
sample
Definition
The sample is the group of people who you select to be in your study.
Term
Time Order
Definition
we can't say a causal relationship exists unless the cause precedes the effect in time.
Term
reductionism
Definition
involves attempts to explain a particular phenomenon in terms of limited and or lower order concepts.
Term
Trend Study
Definition
Type of longitudinal study - examines changes within a population over time. (Comparison of U.S Censuses over a period of decades)
Term
Cohort study
Definition
Type of longitudinal study: a researcher examines specific subpopulations as they change over time, although data may be collected from different members in each set of observations.
Term
panel study
Definition
examines the same set of people each time.
Term
steps of research methods
Definition
operationalization, population and sampling, observations, data processing,analysis, application
Term
conceptualization
Definition
the mental process whereby fuzzy and imprecise notions are made more specific and presise. So you want to study prejudice. What do you mean by "prejudice"? Are there different kinds of prejudice? What are they?
Term
indicator
Definition
an observation that we choose to consider as a reflection of a variable we wish to study. Thus, for example, attending religious services might be considered an indicator of religiosity.
Term
dimension
Definition
a specifiable aspect of a concept. Religiousity for example might be specified in terms of a belief dimension, a ritual dimension, a devotional dimension, a knowledge dimension, and so forth.
Term
real definition
Definition
"essential nature" or the "essential attributes" of some entity. So vague, useless for rigorous inquiry.
Term
nominal definition
Definition
one that is simply assigned to a term without any claim that the definition represents a "real" entity. arbituary - i.e could define compassion as plucking feathers off helpless birds...
Term
operational definition
Definition
operationalization - specifies how a concept will be measured.
Term
nominal measures
Definition
variables whose attributes have only the characteristics of exhaustiveness and mutual exclusiveness. gender, relgious affiliation, political party, birthplace....
Term
ordinal measures
Definition
variables with attributes we can logically rank-order. i.e social class, conservatism, prejudice, -- one is "more" than the other.
Term
interval measures
Definition
the actual distance separating attributes don't have meaning. logical distance between attributes can be expressed in meaningful standard intervals. For example, the distance between 80 and 90 is the same as between 40 and 50. However, 80 degrees F is not twice as hot as 40 degrees.
Term
ratio measures
Definition
a level of measurement describing a varaible with attributes that have all the qualities of nominal, ordinal, and interval measures and in addition are based on a "true zero" point. Age is an example.
Term
nominal, ordinal, interval, ratio
Definition
progressively requiring more information.
Term
precision
Definition
concerns the fineness of distinctions made between the attributes that compose a variable. 43 is more precise than saying someone is in their 40s.
Term
accuracy
Definition
describing someone as born in new england is less precise thatn born in stowe, Ma but if the person is born in Boston - it is more accurate to say they were born in new england even though it isn't as precise a detail.
Term
reliability
Definition
does a particular tech. applied repeatedly to the same object, yield the same results each time?
Term
reliability does not ensure accuracy...
Definition
Term
ways to test reliability
Definition
test-retest method (taking the same measurement twice), split-half method (make more than one measurement of any subtle or complex social concept), using measures that have proved their reliability, appropriately training those collecting data etc.
Term
face validity
Definition
that quality of an indicator that makes it seem a reasonable measure of some variable. that the freq. of attendance at religious services is some indication of a persons religiosity seems to make sense w/o a lot of explanation. It has face validity.
Term
criterion related validity (predictive validity)
Definition
the degree to which a measure relates to some external criterion.
Term
content validity
Definition
the degree to which a measure covers the range of meanings includes within a concept.
Term
index (measure of ordinal variable)
Definition
Construct by accumulating scores assigned to individual attributes. We might measure prejudice by adding up the number of prejudiced statements each respondent agreed with.
Term
scale (measure of ordinal variable)
Definition
assigning scores to patterns of responses, recognizing that some items reflect a relatively weak degree of the variable while others reflect something stronger. (woman are different versus women should not be allowed to vote)
Term
Index construction
Definition
Item Selection: Face Validity, unidimensionality (items relecting religious fundamentalism should not be included in a measure of political conservatism), general or specific, variance

Examination of Empirical Relationships:
bivariate relationship, multivariate relationships.
Index Scoring:
Term
bivariate analysis
Definition
the analysis of two variables simultaneously, for the purpose of determining the empirical relationship between them. The construction of a simple percentage table or the computation of a simple correlation coefficient are examples of bivariate analyses.
Term
multivariate analysis
Definition
the analysis of the simultaneous relationship among several variables. examining simultaneously the effects of age, gender, and social class on religiosity would be an example.
Term
index validation
Definition
item analysis (examine the extent to which the index is related to the individual items it comprises), external validation,
Term
scales
Definition
bogardus social distance scale, thurstone scales, likert scaling, semantic differential, guttman scaling
Term
bogardus social distance scale
Definition
measurement tech. for determining the willingness of people to participate in social relations - of varying degrees of closeness - with other kinds of people.
