Question

Luka’s final exam scores for this semester are 70, 72, 99, 72, and 69. Find the mean and median. Which is a better description of Luka’s typical exam score? Explain your thinking.

Answer 1

The mean is 76.4.
The median is 72.
Mean: 70 + 72 + 99 + 72 + 69 = 382
382 divided by 5 is 76.4.
Median : Order the data set
69, 70, 72, 72, 99
The median is a better description because in the data set there is an outlier (99).
Hope this helped! :D
