Some statistical tests

t-test

-a single dependent variable

-two groups (between subjects design) or two scores for each subject (within subjects design)

-single independent variable

example: Do males score higher on the Herzog Day Care aggression test than females?

Analysis of Variance (ANOVA)

-single dependent variable, but

-more than two independent variables

-or in cases where you have a single independent variable with more than two groups

example: Do Labrador retrievers, Walker coon hounds, and collies differ in their scores on the Herzog Canine Aggression Test

Multivariate Analysis of Variance (MANOVA)

-like ANOVA but use when you have more than on dependent variable

example: Do the three breeds differ in their scores on the Herzog Canine Aggression Test and their fear response to thunder?

Chi-Square

-use for the analysis of categorical data

example: Do males and females differ in their preferences for dogs and cats as pets

Correlation coefficient

-use when you want to see how two variables are related example: What is the relationship between watching TV and aggression in children?

Multiple regression

-use when you want to see how several variables affect a dependent variable

example: how do the amount of watching tv, family income, and gender effect aggression in children)
