The mean is 12.06. The median is 12. The mode is 12. The range is 2.

Work Step by Step

The mean is the average of the data, so add all the numbers and divide by 17 $\frac{11+12+12+12+12+12+12+12+12+12+12+12+12+12+12+13+13}{17}$ $\approx$12.06.The mean is 12.06 Arrange the values from least to greatest(11,12,12,12,12,12,12,12,12,12,12,12,12,12,12,13,13) and find the middle value.The median is 12. The mode is the number that occurs most often. The mode is 12. The range is the difference between the largest and smallest value: 13-11=2.The range is 2
