Chapter 1: Q2. (page 43)

The frequency table at the right shows the ages of people attending a high school play. Make a histogram to display the data.

Short Answer

Expert verified

A histogram is a graphical representation that organizes a group of data points into user-specified ranges. Similar in appearance to a bar graph, the histogram condenses a data series into an easily interpreted visual by taking many data points and grouping them into logical ranges or bins.

Step by step solution

01

Step-1. Apply the concept of the histogram.

A histogram is a graphical representation that organizes a group of data points into user-specified ranges. Similar in appearance to a bar graph, the histogram condenses a data series into an easily interpreted visual by taking many data points and grouping them into logical ranges or bins.

02

Step-2. Analyze the data.

Given data of the ages of people attending a high school play:

  1. On the vertical axis, place frequencies. Label this axis "Frequency".
  2. On the horizontal axis, place the lower value of each interval. Label this axis as 鈥淎ge Group鈥�.
  3. Draw a bar extending from the lower value of each interval to the lower value of the next interval. The height of each bar should be equal to the frequency of its corresponding interval.
