O In the sample, experimental group's self-esteem is higher than the control group. Save Question 20 (1.5 points) To calculate the t-statistic for an independent-samples t-Test, you need an estimated standard error of sample n differences. Which of the following is NOT correct about the estimated standard error? There is only one formula that is used for all independent-samples t-Tests When it is assumed that the variances of two groups are equal, a pooled standard deviation is used to calcul. the estimated standard error When it is assumed that the varlances of thio groups are unequal, the formula is It measures a typical distance bpbieen from sample-mean difference to the population-mean difference.Explanation / Answer
The last point is not correct about standard error
The answer is
• It measures a typical distance between from .........population mean difference .
Note : It is not correct as standard error is the measure of dispersion of sample values in sampling distribution . It is not distance between sample mean and population mean.
