Question

finding distances from the mean
the mean of evelyns scores was 138. complete the chart to find the distances from the mean for each of evelyns scores.
evelyns scores 125 137 138 145 145
distance from the mean x y 0 7 z
x=
y=
z=

Explanation:

Step1: Calculate distance for 125

$|125 - 138|=13$

Step2: Calculate distance for 137

$|137 - 138| = 1$

Step3: Calculate distance for 145 (second occurrence)

Since the mean is 138 and the score is 145, $|145 - 138|=7$

Answer:

$x = 13$
$y = 1$
$z = 7$
