Using a Java simulation tool, students investigate how sample size is related to the amount of variability one sees in the sampling distribution of the mean. Increasing the sample size decreases the variability. Students are assigned questions to answer before using the applet and again after they complete the exploration. They receive feedback after the second set of responses.
