When there are two independent variables, a two-way ANOVA can be applied.
Assumptions from scores in their respective populations are that they are normally distributed and have homogeneous variances. Samples are independently and randomly selected. In comparing the ANOVA with the t-test, the ANOVA can be applied when an independent variable has more than two levels.
One of the most common post hoc tests include Tukey's HSD test. There are others you can find as well.
I hope this will help.
