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

The median = the middle value = 4
The spread = the range of the data = 4 - 2 = 2
