The mean is the best description of the data. If you used a histogram, you would see that the data would form a standard bell curve with no outliers. In these situations, the mean is an effective description of the data.

Work Step by Step

The mean is the average of the data points: $(14+14+15+15+15+16+16)/7 = 15$ 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 15. The mode is the most commonly-occurring value in the set. Here, the answer is 15 since it appears three times.
