Question

the dot plot below shows 4 data points with a mean of 6.
(there is a dot plot with a number line from 1 to 10, with dots at 2, 6, 7, 9)
what is the absolute deviation at 2?
-8
-4
4
8

Explanation:

Step1: Recall absolute deviation formula

Absolute deviation = $|x - \bar{x}|$, where $x$ is the data point, $\bar{x}$ is the mean.

Step2: Substitute given values

$x=2$, $\bar{x}=6$, so $|2 - 6| = |-4|$

Step3: Calculate absolute value

$|-4| = 4$

Answer:
