In the data set below, what is the mean absolute deviation? 9, 3, 5, 7, 3 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 9, 3, 5, 7, 3. Add all the numbers: 9 + 3 + 5 + 7 + 3 = 27. Divide by the number of data points: 27 / 5 = 5.4. Mean = 5.4 Find Deviations: Find the absolute deviations from the mean for each data point. For 9: |9 - 5.4| = 3.6 For 3: |3 - 5.4| = 2.4 For 5: |5 - 5.4| = 0.4 For 7: |7 - 5.4| = 1.6 For 3: |3 - 5.4| = 2.4 List of absolute deviations: 3.6, 2.4, 0.4, 1.6, 2.4 Calculate Mean Deviations: Calculate the mean of the absolute deviations. Add all the absolute deviations: 3.6 + 2.4 + 0.4 + 1.6 + 2.4 = 10.4. Divide by the number of data points: 10.4 / 5 = 2.08. Mean absolute deviation = 2.08 Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. 2.08 rounded to the nearest tenth is 2.1. Final mean absolute deviation = 2.1

Calculate Mean: Calculate the mean of the data set $9, 3, 5, 7, 3$ . Add all the numbers: $9 + 3 + 5 + 7 + 3 = 27$ . Divide by the number of data points: $27 / 5 = 5.4$ . Mean = $5.4$
Find Deviations: Find the absolute deviations from the mean for each data point. $\newline$ For $9$ : $|9 - 5.4| = 3.6$ $\newline$ For $3$ : $|3 - 5.4| = 2.4$ $\newline$ For $5$ : $|5 - 5.4| = 0.4$ $\newline$ For $7$ : $|7 - 5.4| = 1.6$ $\newline$ For $3$ : $|3 - 5.4| = 2.4$ $\newline$ List of absolute deviations: $|9 - 5.4| = 3.6$ $0$
Calculate Mean Deviations: Calculate the mean of the absolute deviations. $\newline$ Add all the absolute deviations: $3.6 + 2.4 + 0.4 + 1.6 + 2.4 = 10.4$ . $\newline$ Divide by the number of data points: $\frac{10.4}{5} = 2.08$ . $\newline$ Mean absolute deviation = $2.08$
Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. $\newline$ $2.08$ rounded to the nearest tenth is $2.1$ . $\newline$ Final mean absolute deviation = $2.1$
