What are some examples of parametric tests?
Parametric tests are statistical tests that assume a specific distribution for the data. Common examples include t-tests, ANOVA, and Pearson's correlation.
Can you explain what a t-test is?
A t-test compares the means of two groups to determine if they are statistically different from each other. It's commonly used when the sample size is small.
What is ANOVA used for?
ANOVA, or Analysis of Variance, is used to compare the means of three or more groups to see if at least one group mean is different from the others.
How does Pearson's correlation work?
Pearson's correlation measures the strength and direction of the linear relationship between two continuous variables, resulting in a value between -1 and 1.
