Question

Quizplus · Accepted Answer

Hypothesis testing is used to determine whether the difference between groups is statistically significant. Correlation coefficients are used to measure the strength and direction of a relationship between two variables, not to determine group differences. Descriptive statistics are used to summarize and describe data, but not specifically to test for group differences. Vector analysis is a mathematical technique used to analyze vectors or matrices, but does not apply to statistical analysis of group differences.
