What are some examples of statistical tests?
There are several types of statistical tests. For example, t-tests compare the means of two groups, while ANOVA tests compare means across multiple groups.
Can you explain when to use a t-test?
A t-test is used when you want to compare the means of two groups to see if they are significantly different from each other.
What about ANOVA? When should I use that?
ANOVA, or Analysis of Variance, is used when comparing the means of three or more groups to determine if at least one group mean is different.
Are there non-parametric tests as well?
Yes, non-parametric tests like the Mann-Whitney U test and Kruskal-Wallis test are used when data doesn't meet the assumptions of parametric tests.
