In the data set below, what is the mean absolute deviation? 5, 9, 7, 5, 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 5, 9, 7, 5, 7. Sum of the data points: 5 + 9 + 7 + 5 + 7 = 33. Number of data points: 5. Mean calculation: 33 / 5 = 6.6.Find deviations: Find the absolute deviations from the mean for each data point. Absolute deviation for 5 = |5 - 6.6| = 1.6. Absolute deviation for 9 = |9 - 6.6| = 2.4. Absolute deviation for 7 = |7 - 6.6| = 0.4. Repeat for all data points.Calculate mean of deviations: Calculate the mean of the absolute deviations. Sum of absolute deviations: 1.6 + 2.4 + 0.4 + 1.6 + 0.4 = 6.4. Mean of absolute deviations: 6.4 / 5 = 1.28.Round to nearest tenth: Round the mean of absolute deviations to the nearest tenth. 1.28 rounded to the nearest tenth is 1.3.

Calculate mean: Calculate the mean of the data set $5, 9, 7, 5, 7$ . $\newline$ Sum of the data points: $5 + 9 + 7 + 5 + 7 = 33$ . $\newline$ Number of data points: $5$ . $\newline$ Mean calculation: $\frac{33}{5} = 6.6$ .
Find deviations: Find the absolute deviations from the mean for each data point. $\newline$ Absolute deviation for $5$ = $|5 - 6.6| = 1.6$ . $\newline$ Absolute deviation for $9$ = $|9 - 6.6| = 2.4$ . $\newline$ Absolute deviation for $7$ = $|7 - 6.6| = 0.4$ . $\newline$ Repeat for all data points.
Calculate mean of deviations: Calculate the mean of the absolute deviations. $\newline$ Sum of absolute deviations: $1.6 + 2.4 + 0.4 + 1.6 + 0.4 = 6.4$ . $\newline$ Mean of absolute deviations: $\frac{6.4}{5} = 1.28$ .
Round to nearest tenth: Round the mean of absolute deviations to the nearest tenth. $\newline$ $1.28$ rounded to the nearest tenth is $1.3$ .
