Mean=44.4, Median=44, Mode=44, Range=18.The mean best describes the data set.

Work Step by Step

The mean best describes the data set because the data set has no outlier. The mean is the average of the data:$\frac{39+52+41+44+47+36+51+44+50+40+53+46+44+35}{14}$=44.4 The median is the middle value. The middle values are 44 and 44 : (44+44)/2=44 The mode is the number that occurs most frequently:44 occurs thrice so it is the mode The range is the difference between the minimum and the maximum:53-35=18.The range is 18
