The estimated standard deviation of the distribution of differences is used to predict the
A) standard error of the mean
B) standard error of difference
C) standard error of the estimate
D) actual standard score

Question

Quizplus · Accepted Answer

The estimated standard deviation of the distribution of differences is used to predict the standard error of difference, which measures the variability between two sample means. A is incorrect because the standard error of the mean is calculated using the sample standard deviation and sample size. C is incorrect because the standard error of the estimate is used in regression analysis to measure the accuracy of the predicted values. D is incorrect because the standard score is a measure of the distance between an individual score and the population mean in units of standard deviation.
