We have 8 classes for different age groups. We also have the frequency for each group.
A histogram is a similar graph to that of a bar chart. However, on the x-axis, we will draw the values for the age classes, and we will draw the frequencies for each class on the y-axis.
1. To graph the histogram, we can start by graphing the corresponding age classes on the x-axis, and the frequencies on each class as follows:
2. Now, we can draw the corresponding frequencies as we can see above.
3. And we can see the resulting histogram, roughly drawn, using the given values of the table in the question. However, we can graph it using a straightedge, and graphing more exact values on the x-axis, and on the y-axis.
Therefore, in summary, we have that the sketch of the histogram, from the given table, can be drawn as follows:
