In the data set below, what is the mean absolute deviation? 8, 8, 9, 4, 6, 7 If the answer is a decimal, round it to the nearest tenth. mean absolute deviation (MAD): _____

Calculate Mean: Calculate the mean of the data set 8, 8, 9, 4, 6, 7. Sum of the data points: 8 + 8 + 9 + 4 + 6 + 7 = 42. Number of data points: 6. Mean: 42 / 6 = 7.Find Deviations: Find the absolute deviations from the mean for each data point. Absolute deviation for 8 = |8 - 7| = 1. Absolute deviation for 8 = |8 - 7| = 1. Absolute deviation for 9 = |9 - 7| = 2. Absolute deviation for 4 = |4 - 7| = 3. Absolute deviation for 6 = |6 - 7| = 1. Absolute deviation for 7 = |7 - 7| = 0.Calculate Mean Deviations: Calculate the mean of the absolute deviations. Sum of absolute deviations: 1 + 1 + 2 + 3 + 1 + 0 = 8. Mean absolute deviation: 8 / 6 = 1.333....Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. 1.333... rounded to the nearest tenth is 1.3.

Calculate Mean: Calculate the mean of the data set $8, 8, 9, 4, 6, 7$ . $\newline$ Sum of the data points: $8 + 8 + 9 + 4 + 6 + 7 = 42$ . $\newline$ Number of data points: $6$ . $\newline$ Mean: $42 / 6 = 7$ .
Find Deviations: Find the absolute deviations from the mean for each data point. $\newline$ Absolute deviation for $8$ = $|8 - 7|$ = $1$ . $\newline$ Absolute deviation for $8$ = $|8 - 7|$ = $1$ . $\newline$ Absolute deviation for $9$ = $|9 - 7|$ = $2$ . $\newline$ Absolute deviation for $4$ = $|8 - 7|$ $0$ = $|8 - 7|$ $1$ . $\newline$ Absolute deviation for $|8 - 7|$ $2$ = $|8 - 7|$ $3$ = $1$ . $\newline$ Absolute deviation for $|8 - 7|$ $5$ = $|8 - 7|$ $6$ = $|8 - 7|$ $7$ .
Calculate Mean Deviations: Calculate the mean of the absolute deviations. $\newline$ Sum of absolute deviations: $1 + 1 + 2 + 3 + 1 + 0 = 8$ . $\newline$ Mean absolute deviation: $\frac{8}{6} = 1.333\ldots$ .
Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. $\newline$ $1.333\ldots$ rounded to the nearest tenth is $1.3$ .
