In the data set below, what is the mean absolute deviation? 3, 2, 9, 4, 1, 2 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 3, 2, 9, 4, 1, 2. Sum of the data points: 3 + 2 + 9 + 4 + 1 + 2 = 21. Number of data points: 6. Mean = 21 / 6 = 3.5.Find Absolute Deviations: Find the absolute deviations from the mean for each data point. Absolute deviation for 3 = |3 - 3.5| = 0.5. Absolute deviation for 2 = |2 - 3.5| = 1.5. Absolute deviation for 9 = |9 - 3.5| = 5.5. Absolute deviation for 4 = |4 - 3.5| = 0.5. Absolute deviation for 1 = |1 - 3.5| = 2.5. Absolute deviation for 2 again = |2 - 3.5| = 1.5.Calculate Mean of Absolute Deviations: Calculate the mean of the absolute deviations. Sum of absolute deviations: 0.5 + 1.5 + 5.5 + 0.5 + 2.5 + 1.5 = 12.0. Mean absolute deviation = 12.0 / 6 = 2.0.

Calculate Mean: Calculate the mean of the data set $3, 2, 9, 4, 1, 2$ . $\newline$ Sum of the data points: $3 + 2 + 9 + 4 + 1 + 2 = 21$ . $\newline$ Number of data points: $6$ . $\newline$ Mean = $\frac{21}{6} = 3.5$ .
Find Absolute Deviations: Find the absolute deviations from the mean for each data point. $\newline$ Absolute deviation for $3$ = $|3 - 3.5| = 0.5$ . $\newline$ Absolute deviation for $2$ = $|2 - 3.5| = 1.5$ . $\newline$ Absolute deviation for $9$ = $|9 - 3.5| = 5.5$ . $\newline$ Absolute deviation for $4$ = $|4 - 3.5| = 0.5$ . $\newline$ Absolute deviation for $1$ = $|1 - 3.5| = 2.5$ . $\newline$ Absolute deviation for $2$ again = $|2 - 3.5| = 1.5$ .
Calculate Mean of Absolute Deviations: Calculate the mean of the absolute deviations. $\newline$ Sum of absolute deviations: $0.5 + 1.5 + 5.5 + 0.5 + 2.5 + 1.5 = 12.0$ . $\newline$ Mean absolute deviation = $\frac{12.0}{6} = 2.0$ .
