Calculate Mean Shirts Prices: Calculate the mean for shirts prices: $15, $21, $18, $19, $24.Mean = (15+21+18+19+24)/5=97/5=19.4
Calculate Mean Pants Prices: Calculate the mean for pants prices: $25, $32, $40, $36, $29.Mean = (25+32+40+36+29)/5=162/5=32.4
Calculate Deviations Shirts: Calculate the deviations from the mean for shirts, then find the absolute values.Deviations: 15−19.4, 21−19.4, 18−19.4, 19−19.4, 24−19.4Absolute deviations: 4.4, 1.6, 1.4, 0.4, 4.6
Calculate Deviations Pants: Calculate the deviations from the mean for pants, then find the absolute values.Deviations: (25−32.4), (32−32.4), (40−32.4), (36−32.4), (29−32.4)Absolute deviations: 7.4, 0.4, 7.6, 3.6, 3.4
Calculate MAD Shirts: Calculate the Mean Absolute Deviation (MAD) for shirts.MAD = (4.4+1.6+1.4+0.4+4.6)/5=12.4/5=2.48
Calculate MAD Pants: Calculate the Mean Absolute Deviation (MAD) for pants. MAD=57.4+0.4+7.6+3.6+3.4=522.4=4.48
Interpret MAD Values: Interpret the MAD values. The MAD for shirts is 2.48, indicating smaller deviations from the mean compared to pants, which has a MAD of 4.48. This suggests that pants prices vary more than shirt prices around their respective means.
