Algebra 1: Common Core (15th Edition)

The mean is the average of the data so you have to add all the values together and divide them by 14: $\frac{39+52+42+44+47+36+51+44+20+40+53+46+44+35}{14}$=$\frac{622}{14}$$\approx$44.4 To find the median you have to arrange the values from least to greatest(35,36,39,40,41,44,44,44,46,47,50,52,52,53). The middle values are 44 and 44.(44+44)/2=44.The median is 44. The mode is the value which occurs the most. 44 occurs thrice so it is the mode. The range is the difference between the largest and the smallest value.53-35=18. The range is 18. The mean best describes the data set since there is no outlier.
