Question

you are studying a weight loss drug. which statistical analysis should you choose to control the weight loss of a treatment group (given drug) and a control group (not given drug). t-test anova linear regression chi-squared

Explanation:

To compare the weight loss between two groups (treatment and control), a t - test is appropriate. ANOVA is for more than two groups, linear regression is for predicting a continuous variable from others, and chi - squared is for categorical data. Here we have two groups (continuous data for weight loss), so t - test is the right choice.
