Frequency distributions are not limited to descriptions of consumer characteristics. Program activity can also be presented categorically. See figures 2 and 3 for examples. Family Type Bar Chart Percent is another useful way of describing data. A frequency count can be converted to percent by dividing the number of units for a particular category by the total number of units and multiplying by 100.
Percents are often more easily understood than the corresponding frequency counts.
Percents can be represented in the same manner as frequency counts. In addition, a pie chart is useful in breaking the total group of people into the percentage of the total represented by each category. See Figure 4 for an example. An average is a way of summarizing all of the information into one number. It can be used with data which is non-categorical numerical data.
