The histogram of frequency distribution is a method used to visually represent the classification of numbers in mathematics. I will teach you how to draw a histogram of frequency distribution.

0 1 First, write a set of numbers randomly, as shown below.

Then calculate the difference between the maximum value and the minimum value in this set of numbers, as shown below.

I will determine the group distance by myself. In my example, I set the group distance as 2, and then divide the gap 14 by 2, which equals 7, and it is determined as 7 groups.

Then start grouping according to your group distance. I divide it into 12 ~ 14, 14 ~ 16, 16 ~ 18, 18 ~ 20, 20 ~ 22, 22.

Finally, draw a histogram of frequency distribution according to your table. The vertical axis is your frequency, that is, how many numbers are in this range, and the horizontal axis is your grouping. If the number in front is too large, the place near the origin can be replaced by wavy lines, as shown below.
