Control Group - In experimental research, a group that, for the sake of comparison, does not receive the treatment the experimenter is interested in.
Crossbreaks - Also called cross- tabulation and cross partitions. A way of arranging data about categorical variables in a matrix so that relations can be more clearly seen. This is not to be confused with a factorial table, in which two or more variables are related to a third.
Data Set- a collection of related data items, such as answers given by respondents to all questions on a survey.
External validity- the extent to which the findings of a study are relevant to subjects and settings beyond those in the study. Another term for generalizability.
Univariate Analysis- studying the distribution of cases of one variable only. For example, studying the ages of a particular group in society but not considering their gender, ethnicity, and so on.
Validity- a term to describe a measurement instrument or test that measures what it is supposed to measure; the extent to which a measure is free of systematic error. For example, a bathroom scale provides a reliable measure but cannot give a valid measure of height.
(These are just a selected number of words from my full glossary I have constructed since the start of the module.)
