Question

Use the image to answer the question.

An illustration shows a bar graph with four bars extending vertically from the x-axis. The horizontal axis ranges from 10 to 13 in increments of 1 and the vertical axis ranges from 0 to 5 in increments of 1. The bar placed at 10 on the x-axis extends to 2 on the y-axis. The bar placed at 11 on the x-axis extends to 4 on the y-axis. The bar placed at 12 on the x-axis extends to 4 on the y-axis. The bar placed at 13 on the x-axis extends to 2 on the y-axis.

The mean = (2 + 4 + 4 + 2) / 4 = 3

To find the median, we need to arrange the data in order: 2, 2, 4, 4. Since there are an even number of values, the median is the average of the two middle values, which are both 2 and 4. So, the median = (2 + 4) / 2 = 3.

The spread is the difference between the maximum and minimum values in the dataset. The minimum value is 2 and the maximum value is 4. So, the spread = 4 - 2 = 2.

Therefore, the mean = 3, the median = 3, and the spread = 2.
