Quizplus · Accepted Answer

When comparing the performance of two groups in an experiment with one experimental group and control group, a t-test would be appropriate. T-tests are used to determine if there is a significant difference between the means of two groups, and are commonly used in experimental research to compare the performance or outcomes of a treatment group to a control group. Standard deviation and correlation coefficient are not appropriate statistical tests for comparing differences between two groups, while analysis of variance (ANOVA) is typically used when comparing more than two groups.
