WebSince T will always be positive, the statement will be true if T is greater than 2.44 or less than -2.44. So, P ( T ≥ 2.44) = P (T ≥ 2.44 + T ≤ -2.44) = 0.24 and P (T ≥ 2.44) = 0.12.

WebAug 11, 2024 · To calculate the sample size using paired t-test, you need to have a prior guess of the mean of d and the standard deviation of d. Thus you need the mean difference rather than the means before and after. Of cause you also need to decide a power and a significands level together with a minimal relevant effect.

Paired T-Test: Formula, Examples & Assumptions StudySmarter
WebConditions required to conduct paired t-test Assumptions for Paired t-test are as follows: The parent population from which the sample is drawn should be normal. The samples should be independent of each other. The sample size should be equal for both the samples, i.e. n 1 = n 2. The dependent variable should be continuos. WebJun 1, 2024 · As a rule of the thumb normally more than 30 pairs are good enough. The minimum sample size is 2 pairs.
