Question

the data set shows the total points that lucie scores in 5 basketball games. 18, 23, 16, 25, 18. what is the mean absolute deviation (mad) of lucies data? enter the answer. the mad is

Explanation:

Step1: Calculate the mean

The mean $\bar{x}=\frac{18 + 23+16+25+18}{5}=\frac{100}{5}=20$.

Step2: Calculate the absolute - deviations

$|18 - 20|=2$, $|23 - 20|=3$, $|16 - 20|=4$, $|25 - 20|=5$, $|18 - 20|=2$.

Step3: Calculate the mean of the absolute - deviations

The MAD $=\frac{2 + 3+4+5+2}{5}=\frac{16}{5}=3.2$.

Answer:

$3.2$
