Q.Match List-I with List-II List-I (Tests) List-II (Description) A. Z-test I. Used for judging the significance of difference between means of two samples. B. t-test II. Used for comparing variance of two independent samples. C. x2-test III. Used for judging the significance of several statistical measures particularly mean. D. F-test IV. Used for comparing a sample variance to a theoretical population variance. Choose the correct answer from the option given below : A B C D A B C D
Correct answer: III I IV II
Explanation
Correct match is- Z-test: A statistical test used to determine whether the means of two populations are different when the population variances are known and the sample size is large. t-test : A statistical test used to determine whether there is a significant difference between the means of two groups based on a sample of data. Chi-square test: A statistical test used to determine whether there is a significant association between two categorical variables. It compares the observed frequencies to the expected frequencies. F-test: A statistical test used to compare the variances of two samples to determine if they are significantly different from each other. It is often used in analysis of variance (ANOVA) to test the equality of means across multiple groups.
