Question

chann is a video game designer. on monday, she tests a puzzle from her new game, code quest, with 5 players. the dot - plot shows the time it takes them to complete the puzzle. what is the mean of the times? mean = 14 minutes mean absolute deviation (mad) describes how spread out a data set is. to find the mad, find the distance of each data value from 14. then find the average of the distances. what is the mad of the times? you can use a calculator to help. mad = minutes

Explanation:

Step1: List data values

The data values from the dot - plot are 10, 14, 16, 18, 19.

Step2: Calculate absolute deviations

For 10: $|10 - 14|=4$; for 14: $|14 - 14| = 0$; for 16: $|16 - 14|=2$; for 18: $|18 - 14| = 4$; for 19: $|19 - 14|=5$.

Step3: Calculate average of absolute deviations

$\frac{4 + 0+2 + 4+5}{5}=\frac{15}{5}=3.2$

Answer:

3.2
