Question

The data below shows average number of text messages a group of students send per day. What is a histogram that represents the data? 20 5 8 22 10 1 7 15 16 12 15 6 13 8

Answer 1

To draw a histogram, you need two axes. The horizontal axis is the day and the vertical axis is the number of text messages. For the first day, there are 20 text messages. This is represented by a bar starting from the horizontal axis labeled Day 1 going up to the point where the vertical axis indicates 20 text messages. This is done for the rest of the data.

So this is what it would look like with all the information.

Hope this Helps!!

Answer 2

Answer:

The graph is attached.

Step-by-step explanation:

The range of this data is the highest value, 22, subtracted by the lowest value, 1:  22-1 = 21.

Using boundaries, the first bar would go from 0.5-3.5; the second from 3.5-6.5; the third from 6.5-9.5; the fourth from 9.5-12.5; the fifth from 12.5-15.5; the sixth from 15.5-18.5; the seventh from 18.5-21.5; and the eighth from 21.5-24.5.

The frequency of the first bar, its height, would be 1; the height of the second bar is 2; the height of the third bar is 3; the height of the fourth bar is 2; the height of the fifth bar is 3; the height of the sixth bar is 1; the height of the seventh bar is 1; and the height of the eighth bar is 1.
