What Is The Minimum Sample Size For T-Test

What Is The Minimum Sample Size For T-Test. As is usual in statistics the answer is it depends. For a test with \alpha = 0.05 and \beta = 0.10, the minimum sample size required for the test is n = (1.645 + 1.282)^2 = 8.567 \approx 9 \,.

To ensure the power in the normality test, sufficient sample size is . There is no minimum sample size for the t test to be valid other than it be large enough to calculate the test statistic. The smallest sample size investigated in this study was 5 versus 15.

To ensure the power in the normality test, sufficient sample size is .

To ensure the power in the normality test, sufficient sample size is . If sample size is less than 30 the . To ensure the power in the normality test, sufficient sample size is . As is usual in statistics the answer is it depends.
