Can you explain when to use a t-test?
A t-test is used to compare the means of two groups to see if they are statistically different from each other.
What about ANOVA? When is it appropriate?
ANOVA is used when comparing the means of three or more groups to determine if at least one group mean is different.
How do I choose between a t-test and ANOVA?
