Experimental Design
Type of design where the IV is manipulated
100
Chi-square
What is a statistic that compares the tallies or counts of categorical responses between two (or more) independent groups. A statistic whose IVs and DVs are categorical
200
Independent Variable
The predictor or causal variable in the study
200
Between-subjects design
Type of design using independent groups
200
Correlated (Dependent) t-test
What is a method to evaluate the differences in means between two groups when the groups are paired in some way
300
Alternative Hypothesis
It states that the differences in scores between conditions are due to the action of the independent variable.
300
Correlational Design
What is a design that examines the relationship between two variables. Inferences of causation may not be made.
300
Independent-sample t-test
What is a method to evaluate the differences in means between two groups when the groups are independent, or not related.

Levene's Test
The test used to determine the assumption of equal variances?
400
Sampling
Involves selecting a relatively large number of units from a population, or from specific subgroups of a population, in a random manner where the probability of inclusion for every member of the population is determinable.

One-way ANOVA
What is a test that allows for comparison of means between two or more groups
500
Nonparametric Statistics
What is a statistic whose interpretation does not depend on the sample fitting any distribution parameters
500
Repeated Measure Design
The ultimate goal of this type of design is to determine individuals' change of attitude before, during, and after intervention
500
Two-way ANOVA
What is a test that evaluates the effect of two independent variables and the interaction between them on a dependent variable
