In the data set below, what is the mean absolute deviation? 1, 7, 9, 2, 9 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 1, 7, 9, 2, 9. Sum of the data points: 1 + 7 + 9 + 2 + 9 = 28. Number of data points: 5. Mean = 28 / 5 = 5.6.Find Deviations: Find the absolute deviations from the mean for each data point. Absolute deviation for 1 = |1 - 5.6| = 4.6. Absolute deviation for 7 = |7 - 5.6| = 1.4. Absolute deviation for 9 = |9 - 5.6| = 3.4. Absolute deviation for 2 = |2 - 5.6| = 3.6. Absolute deviation for 9 = |9 - 5.6| = 3.4.Calculate Mean Deviations: Calculate the mean of the absolute deviations. Sum of absolute deviations: 4.6 + 1.4 + 3.4 + 3.6 + 3.4 = 16.4. Mean absolute deviation = 16.4 / 5 = 3.28.Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. 3.28 rounded to the nearest tenth is 3.3.

Calculate Mean: Calculate the mean of the data set $1, 7, 9, 2, 9$ .
Sum of the data points: $1 + 7 + 9 + 2 + 9 = 28$ .
Number of data points: $5$ .
Mean = rac{28}{5} = 5.6.
Find Deviations: Find the absolute deviations from the mean for each data point. $\newline$ Absolute deviation for $1$ = $|1 - 5.6| = 4.6$ . $\newline$ Absolute deviation for $7$ = $|7 - 5.6| = 1.4$ . $\newline$ Absolute deviation for $9$ = $|9 - 5.6| = 3.4$ . $\newline$ Absolute deviation for $2$ = $|2 - 5.6| = 3.6$ . $\newline$ Absolute deviation for $9$ = $|9 - 5.6| = 3.4$ .
Calculate Mean Deviations: Calculate the mean of the absolute deviations. $\newline$ Sum of absolute deviations: $4.6 + 1.4 + 3.4 + 3.6 + 3.4 = 16.4$ . $\newline$ Mean absolute deviation = $\frac{16.4}{5} = 3.28$ .
Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. $3.28$ rounded to the nearest tenth is $3.3$ .
