Match the statistical tests with their explanations:
List I (Statistical Test) | List II (Explanation) |
A. Z-Test | I. Tests the significance of the association between two attributes |
B. Chi-Square | II. Compares the difference in the mean values of two independent sample groups (Non-parametric data) |
C. ANOVA | III. Tests the significance of the difference between average of two large-sized sample groups (Parametric data) |
D. Mann-Whitney Test (U-test) | IV. Compares the difference in the mean values of more than two sample groups (Parametric data) |
Codes:
· Z-Test (A-III): Used for large samples (n > 30) to compare means.
· Chi-Square Test (B-I): Used to measure the relationship between categorical variables.
· ANOVA (C-IV): Compares means of more than two groups.
· Mann-Whitney U-Test (D-II): A non-parametric test comparing two independent groups.
