Mean: 12 Median: 11 Mode: 10
Work Step by Step
The mean is the average of the data points: $(12+10+9+15+16+10)/6 = 12 $ The median is given by the middle data points. Order the numbers from least to greatest, and cross out the greatest and the least number. Repeat this process until you obtain the median, which is 11. The mode is the most commonly-occurring value in the set. Here, the answer is 10 since it appears two times.
