What statistical analysis type would you use for the following data (2 sampled unpaired t test, 1 sample z test, logistic regression, etc).

Answer #1

CASE -1

Assuming that time is the dependent variable and type is the independent variable

It is clear that time is continuous variable and type is a categorical variable

When we have dependent variable as continuous and independent variable as categorical, then we use ANOVA for testing purpose.

CASE -2

Now, suppose that we assuming that time is the independent variable and type is the dependent variable

It is clear that time is continuous variable and type is a categorical variable

When we have independent variable as continuous and dependent variable as categorical, then we use logistic regression for testing purpose.
