A histogram is a bar graph which shows frequency distribution.
To make a histogram, follow these steps:
On the vertical axis, place frequencies.
Label this axis "Frequency".
On the horizontal axis, place the lower value of each interval.
Label this axis with the type of data shown (price of birthday cards, etc.)
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.

Answer:
Step-by-step explanation:
To create a histogram, the data need to be grouped into class intervals. Then create a tally to show the frequency (or relative frequency) of the data into each interval. The relative frequency is the frequency in a particular class divided by the total number of observations.
