The table shows the height of pea plants in centimeters after 6 weeks of growth. Each plant started at a height of 5 centimeters. Two
planting soils were tested. Which statement BEST compares the mean absolute deviation (MAD) of the two sets of data?
Planting soil 1 plant height:
15.10.19.17.16, 12, 20, 22, 18.35
Planting soil 2 plant height:
16, 17, 10, 12, 18, 17, 14, 15, 17. 23
Planting soil 1 showed less variability, since Planting soil 1 MAD is
approximately 2.0 times greater than planting soil 2 MAD.
Planting soil 2 showed less variability, since Planting soil 2 MAD is
approximately 2.0 times greater than planting soil 1 MAD.
Planting soil 1 showed greater variability, since Planting soil 1 MAD is
approximately 1.8 times greater than planting soil 2 MAD.
Planting soil 2 showed greater variability, since Planting soil 2 MAD is
approximately 1.8 times greater than planting soil 1 MAD.
