Dox Chapter 9 End-of-Chapter Problems Due Tomorrow at 4 PM EDT to Attempts: 2. Chapter 9 - End-of-chapter question 2 A sample of n = 16 scores has a mean of M-56 and a standard deviation of s 20. Explain what is measured by the sample standard deviation. The sample standard deviation describes thevariability this case, the standard distance between of thescores in the sample 0 In and is 20 points. Compute the estimated standard error for the sample mean, and explain what is measured by the standard error. and The standard error provides a measure of points. . In this case, the estimated standard error is

Explanation / Answer

Standard error of the mean is given by 20/sqrt(n) = 20/sqrt(16) = 5

Standard error is a statistical term that measures the accuracy with which a sample represents a population.
