Question by Rosie: how do a one-way ANOVA and a t-test difer in what type of data we can analyze?
this is for my psychology research methods class.

Also, another question:

in a 2X2 ANOVA design, how many independent variables are there? can we know the number of dependent variables in this design from the information provided?

Best answer:

Answer by Orai79
A t-test only tests whether there is a significant difference between two group means. A one-way ANOVA can test whether there are differences between more than two group means.

In a 2×2 design, there are two independent variables, each of which has two levels. From the design, no, you cannot tell how many dependent variables there are.
