Easy way to remember/distinguish t-test vs ANOVA vs chi-square?

I've never really understood these terms, the definitions all seem vague and overly simplified in comparison to the questions on them that show up on nbmes.

how do i remember them and be able to know which is for which classical situation on an nbme?

thanks.

Really easy man... just like this:

2 means and 2 SD = t-test

>2 means and > 2 SD= ANOVA (one-way ANOVA, two-ways ANOVA)

t-test = compares the SD and mean of 2 groups (different from Chi-square, it compares characteristics among 2 groups)

ANOVA = compare the SD and the mean of more than 2 groups. (In the setting of step 1, ANOVA its just like a t-test but for compare >2 groups)
