Use the image to answer the question.

A horizontal number line with arrows at both ends is titled at the top as Soccer Team A. Below the line is the title, Number of Goals per Game. The line is numbered 0 to 5 in increments of 1 and has a total of 10 closed points plotted.

A soccer team tracks the number of goals they score in a game on the dot plot. Complete the table to record the deviation of each data point.

To calculate the deviation for each data point in a dot plot, you first need to determine the mean (average) of the data points. Since I cannot see the image or the actual data points plotted on the number line, I will guide you on how to calculate deviations generally.

  1. Calculate the Mean:

    • Add all of the data points together.
    • Divide the total by the number of data points.
  2. Calculate the Deviation for Each Data Point:

    • For each data point, subtract the mean from the data point value. This will give you the deviation for each data point.
    • The formula is: \[ \text{Deviation} = \text{Data Point} - \text{Mean} \]
  3. Complete the Table:

    • Use the above calculations to fill in the "Deviation" row of your table under the respective data points.

If you can provide the actual data points from the image, I can help calculate the deviations more specifically!
