A t-test is generally used to analyze data with __two___ level(s), and an ANOVA is generally used to analyze data with ___more than two__ level(s).

c. two; more than two (option c is correct)

#For example

We would use a t test if we wished to compare the reading achievement of boys and girls. With a t test, we have one independent variable and one dependent variable. The independent variable (gender in this case) can only have two levels (male and female). The dependent variable would be reading achievement. If the independent had more than two levels, then we would use a one-way analysis of variance (ANOVA).
