Question

practice solving problems involving absolute deviation. the mean for the data in the dot plot is 5. what is the absolute deviation for the data point at 7? (dot plot with points at 1, 4, 5, 7, 8)

Explanation:

Step1: Recall absolute deviation formula

The formula for absolute deviation of a data point \( x \) from the mean \( \mu \) is \( |x - \mu| \).

Step2: Identify values

Here, the data point \( x = 7 \) and the mean \( \mu = 5 \).

Step3: Calculate absolute deviation

Substitute into the formula: \( |7 - 5| = |2| = 2 \).
