General issues
This type of longitudinal study examines change with a specific population over time.
What is cohort study
The working definition of a concept or term.
What is conceptual definition
Consistency in measurement.
What is reliability
Selecting some units of a larger population.
What is sampling
Sampling in which the probability than an element will be included in the sample is not known.
What is non-probability sampling.
When findings from a study about cause and effect can be generalized.
What is external validity
Variables whose attributes can only be rank-ordered (i.e., higher to lower)
What is ordinal
Accuracy in measurement.
What is validity
The population to which the research wants to generalize the results to.
What is target population
This probability sampling design is when every possible combination of cases has an equal chance of being included in the sample.
What is simple random sampling
Making assertions about individuals based on the examination of other, larger, units of analyses
What is ecological fallacy
A single observable measure. One question, one variable.
What is indicator
This method to assess measurement quality makes a personal judgement that a concept is being adequately measured in a study.
What is face validity.
The difference between the population value and the sample estimate of the value.
What is sampling error
This non-probability sampling design selects a specific number of cases based on what is easy and accessible.
What is convenience sampling
This type of explanation or approach requires logic to be credible and consideration of alternative explanations in order to make causal arguments.
What is idiographic
When every potential observation can classified into one of the attributes of a variable.
What is mutually exclusive
This method for assessing measurement quality makes the same measurement more than once in a study.
What is test-retest method.
A list of elements in a population used to draw ones sample.
What is sampling frame.
This non-probability sampling design asks respondents to refer others to the study who are socially linked to them in a meaningful way.
What is network sampling.
The unit of analysis in a study examining if rock music has more lyrical references to drugs than country music.
What is social artifact
What is Likert scale.
This method for assessing measurement quality compares the measure with logical and expected relationships among other variables.
What is construct validity
When all members of a population have an equal chance of being selected in the sample.
What is equal probability of selection method or EPSEM
This probability sampling design first divides the population in two or more groups, then takes a simple random sample from all groups, then combines them into one sample.
What is stratifies sampling
