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.
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
