What are some examples of hypothesis tests?
Hypothesis tests are statistical methods used to make inferences about populations based on sample data. Examples include t-tests, chi-square tests, and ANOVA.
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 sizes are small.
What about a chi-square test?
A chi-square test assesses whether there is a significant association between categorical variables. It compares observed frequencies to expected frequencies.
When should I use ANOVA?
ANOVA, or Analysis of Variance, is used when comparing the means of three or more groups to see if at least one group mean is different.
