Q. In the data set below, what is the mean absolute deviation? 7,9,5,4,8,2,7If the answer is a decimal, round it to the nearest tenth. mean absolute deviation (MAD): __
Arrange Data in Ascending Order: Arrange the data set in ascending order.Data set in order: 2,4,5,7,7,8,9.
Calculate Mean: Calculate the mean of the data set.Mean = (2+4+5+7+7+8+9)/7=42/7=6.
Calculate Absolute Deviations: Calculate the absolute deviations from the mean.Absolute deviations: ∣2−6∣=4, ∣4−6∣=2, ∣5−6∣=1, ∣7−6∣=1, ∣7−6∣=1, ∣8−6∣=2, ∣9−6∣=3.
Calculate Mean Absolute Deviation: Calculate the mean of these absolute deviations.Mean absolute deviation = (4+2+1+1+1+2+3)/7=14/7=2.0.
