In the data set below, what is the mean absolute deviation? 2, 5, 9, 9, 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, 5, 9, 9, 5. Sum of data points: 2 + 5 + 9 + 9 + 5 = 30. Number of data points: 5. Mean = 30 / 5 = 6.Calculate Absolute Deviations: Calculate the absolute deviations from the mean for each data point. Absolute deviation for 2 = |2 - 6| = 4. Absolute deviation for 5 = |5 - 6| = 1. Absolute deviation for 9 = |9 - 6| = 3. Absolute deviation for another 9 = |9 - 6| = 3. Absolute deviation for another 5 = |5 - 6| = 1.Calculate Mean of Absolute Deviations: Calculate the mean of the absolute deviations. Sum of absolute deviations: 4 + 1 + 3 + 3 + 1 = 12. Mean absolute deviation = 12 / 5 = 2.4.Round Mean Absolute Deviation: Round the mean absolute deviation to the nearest tenth. 2.4 rounded to the nearest tenth is 2.4.

Calculate Mean: Calculate the mean of the data set $2, 5, 9, 9, 5$ .
Sum of data points: $2 + 5 + 9 + 9 + 5 = 30$ .
Number of data points: $5$ .
Mean = rac{30}{5} = 6.
Calculate Absolute Deviations: Calculate the absolute deviations from the mean for each data point. $\newline$ Absolute deviation for $2$ = $|2 - 6|$ = $4$ . $\newline$ Absolute deviation for $5$ = $|5 - 6|$ = $1$ . $\newline$ Absolute deviation for $9$ = $|9 - 6|$ = $3$ . $\newline$ Absolute deviation for another $9$ = $|9 - 6|$ = $3$ . $\newline$ Absolute deviation for another $5$ = $|5 - 6|$ = $1$ .
Calculate Mean of Absolute Deviations: Calculate the mean of the absolute deviations. $\newline$ Sum of absolute deviations: $4 + 1 + 3 + 3 + 1 = 12$ . $\newline$ Mean absolute deviation = $\frac{12}{5} = 2.4$ .
Round Mean Absolute Deviation: Round the mean absolute deviation to the nearest tenth. $2.4$ rounded to the nearest tenth is $2.4$ .
