Question

The dot plot below shows how many laps each student in Coach Toni's gym class ran one day.

What is the mean absolute deviation of the data set shown?
A. 30
B. 12.5
C. 5
D. 7

Answer 1

12.5 because you add up all of the number of laps. Then you divide that from how laps there were.

Answer 2

`\underbrace{5;5;5;5;10;10;15;15;20;35}_(10)\\\\5\cdot4+10\cdot2+15\cdot2+20+35=125\\\\(125)/(10)=12.5\leftarrow\boxed{B}`
