Quizplus · Accepted Answer

A bell-shaped distribution with a large number of scores in the middle is characteristic of a normal curve. A normal curve is a type of distribution that is symmetric, with the mean, median, and mode all being equal. Positive and negative skew refer to distributions that are not symmetric and have more scores on one side of the peak than the other. A histogram is a graphical representation of a frequency distribution.
