Make a dot plot that shows the number of hours of sleep people get based on different age groups:
Age Group | Number of Hours of Sleep
10-20 | 7, 6, 8, 7, 8
21-30 | 6, 7, 8, 8, 7
31-40 | 7, 6, 6, 7, 8
41-50 | 7, 7, 6, 8, 7
51-60 | 7, 8, 6, 8, 6
To make a dot plot showing the number of hours of sleep people get based on different age groups, you can follow these steps:
Step 1: Create a number line for the range of hours of sleep you have in your data set. In this case, it seems to be between 6 and 8.
Step 2: Draw a horizontal line and label it with the age groups on the left side, and the number line on the right side.
Step 3: Plot a dot at the appropriate location for each data point. Each dot will represent the number of hours of sleep for a specific individual.
Here's an example of how the dot plot would look based on the data you provided:
Number of Hours of Sleep
Age Group | 6 . 7 . 8
-----------------------------------------
10-20 | ● ● ●
21-30 | ● ● ●
31-40 | ● ● ●
41-50 | ● ● ●
51-60 | ● ● ●
In this dot plot, the dots represent the number of hours of sleep for each individual within each age group. For example, in the 10-20 age group, there are three dots at the 7-hour mark, two dots at the 8-hour mark, and no dots at the 6-hour mark.
Remember, dot plots are an effective way to display data because they show the frequency of each data point, allowing you to easily compare between different age groups.
