CPM Homework Help : CC3 Problem 1-59

Kelly asked some of her classmates how many hours of sleep they get on school nights. Here are the results:

$6,8,7\frac{1}{2},9,8,8,8,$ $9,9,10,6,8\frac{1}{2},9,7,8$

Copy the set of axes below and create a histogram for the data. (Refer to the glossary in the eBook for assistance, if needed.)

First quadrant graph, x axis labeled, Hours of Sleep, scaled by ones from 0 to 11, y axis labeled, Number of Students, scaled by ones from 0 to 8.

Step 1:

Determine bins appropriate to your data (how wide each bar will be). For this problem use one hour bins.

Hint:

Think of each bin as containing all the values between the number on the left and the number on the right. For example, a value of $6.5$ would be counted with the bar between $6$ and $7$ , but a value of $7.0$ would be counted with the bar between $7$ and $8$ .

Step 2:

Count the number of values in each bin. Draw a bar for each bin. The height of the bar corresponds to the number of values in the bin.
