deviation of the mean, is a method used to estimate the standard deviation of a sampling distribution. To understand this, first we need to understand why a sampling distribution is required.

the absence of the complete database, we may wish to estimate by taking a random sample of, say, n=25 students and computing the sample average (call this ). Suppose =3.05. Now, unless we got really lucky with the random sample, chances are is not equal to 3.05; i.e. the estimate missed. By how much? On the average, a random variable misses the mean by one standard deviation. From the previous section, the standard deviation of is , where sigma is the population SD for individuals. Therefore, is the expected size of the miss when is used to estimate . Typically, is called the standard error of estimation of the mean , or simply standard error of the mean. `Standard error' will often be denoted by the abbreviation SE throught this manuscript. In the absence of the population database for 23000 WMU students, we do not know nor . Thus, we cannot calculate . In this situation, is typically replaced by the standard deviation S of the sample. The resulting quantity is called the estimated standard error of the mean. Returning to the GPA example, suppose that the sample of n=25 students yielded an average GPA of 3.05 and a standard deviation of .40. Then the WMU population average GPA is estimated as 3.05 with an estimated standard error of . Example 3. What is the average length of stay for undergraduate students at WMU? a. Suppose 25 graduating students were randomly selected and asked about their length of stay. Suppose that the sample averaged 5.3 years, with an SD of 1.5 years. Then the WMU average stay is estimated as years give or take years or so. b. A second sample of 100 students were interviewed. The mean and SD for the second sample were also 5.3 years and 1.5 years, respectively. Calculate an estimate for the WMU average stay and provide a standard error for your estimate. Similar to the SE for proportions, the formula for the SE of the mean has the sample size (i) in the denominator, and (ii) inside the squareroot sign. Therefore, increasing the sample size by a factor of 4
