In the chapter reading, you worked with a very small population and sample size and learned that distributions of sample means are normally distributed and have a mean equal to the population mean () and a standard deviation equal to the standard error of the mean (SEM).2 Creating an actual distribution of sample means from raw data is not possible with larger populations and sample sizes because doing so would be too time consuming and you rarely have access to an entire population of scores. Fortunately, the CLT describes the characteristics of all distributions of sample means. This activity uses an online simulation to help you better understand distributions of sample means and why it is important. Suppose that the average height of women in the United States is 64.5 inches. If you obtained a random sample of 25 women from this population, what is your best guess for the mean height of the sample
