Analysis of variance (ANOVA) is the best choice for a study with more than two experimental/control groups and more than one independent variable. ANOVA is used to determine if there is a statistically significant difference between the means of three or more groups. It allows for multiple comparisons and can test for interactions between the independent variables. The chi-squared test is used to test for independence between two categorical variables, the t test is used to compare the means of two groups, and the correlation coefficient is used to measure the strength and direction of a relationship between two variables.
