Activity Overview
In this activity, students will recognize that elements of a sample from a normal population will vary symmetrically around the mean of the population, with values near the mean occurring more frequently than those further from the mean. Also, students will recognize that the means of different samples from a normal population will vary symmetrically around the mean of the population, with values near the mean occurring more frequently than those further from the mean, but in a narrower interval than that of individual elements of the population.
