To calculate the difference between the mean and the median of the data in a dot plot, you would first need to find the mean and median values of the data. However, as you haven't provided the actual dot plot or the data points, I cannot perform these calculations.
Here’s how you can find the mean and median yourself:
-
Mean: Add all the data points together and divide by the total number of points.
\[ \text{Mean} = \frac{\text{Sum of all data points}}{\text{Number of data points}} \]
-
Median: Arrange the data points in ascending order. If there’s an odd number of data points, the median is the middle value. If even, it's the average of the two middle values.
-
Difference: Subtract the median from the mean.
Now, based on your available options, calculate the difference to find out which answer (A, B, C, or D) is correct.
If you provide me with the specific data from the dot plot, I can help you calculate the mean, median, and their difference.
