| List - I | List - II |
|---|---|
| I. A non-parametric technique to compare obtained results with those to be expected | 1. Z test |
| II. A statistical test to determine the significant difference between the sample mean and population mean | 2. Correlation |
| III. A statistical technique to establish the relationship among variables | 3. F-Ratio |
| IV. A test to assess the significant difference in the means of more than two groups | 4. Chi-square Test |
Codes : I II III IV
Answer: A
The matching is the non-parametric technique to compare obtained results with those expected: chi-square test; the test for the difference between a sample mean and a population mean: Z test; the technique to establish the relationship among variables: correlation; and the test for the difference between the means of more than two groups: F-ratio. This gives the code 4 1 2 3. The other codes pair the chi-square test with a parametric purpose, or the F-ratio with only two groups, which is the job of a t or Z test.
