In the data set below, what is the mean absolute deviation? 2, 9, 5, 9, 3, 5 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 2, 9, 5, 9, 3, 5. Sum of data points: 2 + 9 + 5 + 9 + 3 + 5 = 33. Number of data points: 6. Mean = 33 / 6 = 5.5.Find Deviations: Find the absolute deviations from the mean for each data point. Absolute deviation for 2 = |2 - 5.5| = 3.5. Absolute deviation for 9 = |9 - 5.5| = 3.5. Absolute deviation for 5 = |5 - 5.5| = 0.5. Absolute deviation for 9 = |9 - 5.5| = 3.5. Absolute deviation for 3 = |3 - 5.5| = 2.5. Absolute deviation for 5 = |5 - 5.5| = 0.5.Calculate Mean Deviations: Calculate the mean of the absolute deviations. Sum of absolute deviations: 3.5 + 3.5 + 0.5 + 3.5 + 2.5 + 0.5 = 14. Mean absolute deviation = 14 / 6 = 2.333.Round Mean Deviations: Round the mean absolute deviation to the nearest tenth. 2.333 rounded to the nearest tenth is 2.3.

Calculate Mean: Calculate the mean of the data set $2, 9, 5, 9, 3, 5$ . $\newline$ Sum of data points: $2 + 9 + 5 + 9 + 3 + 5 = 33$ . $\newline$ Number of data points: $6$ . $\newline$ Mean = $\frac{33}{6} = 5.5$ .
Find Deviations: Find the absolute deviations from the mean for each data point. $\newline$ Absolute deviation for $2$ = $|2 - 5.5| = 3.5$ . $\newline$ Absolute deviation for $9$ = $|9 - 5.5| = 3.5$ . $\newline$ Absolute deviation for $5$ = $|5 - 5.5| = 0.5$ . $\newline$ Absolute deviation for $9$ = $|9 - 5.5| = 3.5$ . $\newline$ Absolute deviation for $3$ = $|3 - 5.5| = 2.5$ . $\newline$ Absolute deviation for $5$ = $|5 - 5.5| = 0.5$ .
Calculate Mean Deviations: Calculate the mean of the absolute deviations. $\newline$ Sum of absolute deviations: $3.5 + 3.5 + 0.5 + 3.5 + 2.5 + 0.5 = 14$ . $\newline$ Mean absolute deviation = $\frac{14}{6} = 2.333$ .
Round Mean Deviations: Round the mean absolute deviation to the nearest tenth. $2.333$ rounded to the nearest tenth is $2.3$ .
