12 questions
Describe two methods, other than a normal probability plot, that can be used to assess the normality of a dataset.
Explain how comparing the mean and median of a dataset can provide insight into whether the data is approximately normally distributed.

Quick comprehension check
“A dataset has a mean of 102 and a median of 98. A normal probability plot shows points that generally follow a straight line, but with some slight deviations at the ends. Is the data approximately normally distributed? Explain your reasoning. A histogram of a dataset appears roughly symmetric and bell-shaped. The mean and median are nearly identical. However, the normal probability plot shows a distinct curve. Is the data approximately normally distributed? Explain your reasoning. A dataset has a mean of 50 and a median of 75. The normal probability plot shows points clustered randomly with no clear pattern. Is the data approximately normally distributed? Explain your reasoning.”
