 A bar graph can be used to display and compare data.  The scale should include all the data values and be easily divided into equal intervals.

Histogram is a bar graph that shows the frequency of data within equal intervals. There is no space in between the bars.

The table below shows the number of hours students watch TV in one week. Make a histogram of all the data. Number of hours of TV III6II1 IIII - IIII 7IIII2 III8 3 IIII9 IIII - I IIII - I4 IIII - III IIII - III5

Step 1 Make a frequency table of the data. Be sure to use equal intervals.Frequency Number of hours of TV III6II1 IIII - IIII7IIII2 III8IIII - IIII3 IIII9 IIII - I4 IIII - III5

Step 2 Choose an appropriate scale and interval for the vertical axis. The greatest value on the scale should be at least as great as the greatest frequency. Step 3 Draw a bar for each interval. The height of the bar is the frequency for that interval. Bars must touch but not overlap. Label the axes and give the graph title
