Which of the following statements is false?
A frequency distribution counts the number of observations that fall into each of a series of intervals, called classes that cover the complete range of observations.
The intervals in a frequency distribution must not overlap to ensure that each observation is assigned to one interval only.
The number of class intervals in a frequency distribution must be the same as the number of observations.
Although the frequency distribution provides information about how the numbers in the data set are distributed, the information is often more easily understood and imparted by drawing a histogram.
