Which statistical test is used to compare mean of two identical group?
Show Hint
- ANOVA
- Sample t test
- Paired t test
- Pooled t test
The Correct Option is C
Solution and Explanation
The paired t-test is a statistical method used to compare the means of two related (i.e., identical or matched) groups. It is used when the same subjects are measured twice. for example, before and after a treatment, or under two different conditions. The test determines whether the average difference between paired observations is significantly different from zero.
In the context of GPAT, it is essential for comparing pre- and post-treatment effects or evaluating crossover study designs in biostatistics and clinical trials.
Other options:
(A) ANOVA (Analysis of Variance) — Used when comparing means of more than two groups.
(B) Sample t test (Unpaired/Independent t test) — Used to compare the means of two independent groups.
(D) Pooled t test — A form of unpaired t-test that assumes equal variances in two independent samples.
