Question

What statistical analysis procedure would be appropriate in each of the following situations? Assume your independent variables are between-participants independent variables situations?

You have one quantitative dependent variable and three categorical independent variables.

You have one quantitative dependent variable and one categorical independent variable, and one quantitative independent variable/covariate.

.

Answer 1

For one quantitative dependent variable and three categorical independent variables, we may use:

Factorial Logistic Regression (used to predict a nominal dependent variable given one or more independent variables.)

For one quantitative dependent variable and one categorical independent variable, we may use:

Chi-square Test (used to determine whether there is a significant association between two categorical variables from a single population.) For one quantitative dependent variable and one quantitative independent variable/covariate, we may use: Independent Sample T-test (compares the means of two independent groups in order to determine whether there is statistical evidence that the associated population means are significantly different.)
