Draw a bar for each interval that is used in the frequency table and make the height of each bar equal to the frequency of the interval.
We want to draw a histogram to represent the given set of data. Let's take a look at the frequency table for this data set.
| Test Scores | ||
|---|---|---|
| Percent | Tally | Frequency |
| 50-59 | | | 1 |
| 60-69 | || | 2 |
| 70-79 | |||| | 4 |
| 80-89 | |||| |||| | | 11 |
| 90-99 | |||| || | 8 |
Let's construct the histogram. We will draw a bar for each interval from the frequency table and make the height of each bar equal to the frequency of the interval. Keep in mind that the bars should touch but not overlap. Do not forget to label the axes!
