Exam 2: Exploring Data: Frequency Distributions and Graphs

The frequency distribution scores ranged from 0 to 100. Low scores were infrequent, there were a moderate number around 50, and near 100 scores were quite frequent. The distribution is

A distribution with two humps is called a skewed distribution.

Suppose a frequency distribution with a range of 0 to 100 was positively skewed. The greatest frequency of scores would be expected around
