The stemandleaf plot shows the heights in centimeters of Teddy Bear sunflowers grown in two different types of soil.
Soil A
65,62,61,61
75,71,70
82,81
90
Soil B
59
63,69
70,72,73,76,77,78
83
a) Describe the overlap of the two sets of data.
b) Calculate the mean of each data set.
1438/20 = 71.9
The mean of each data set is 71.9.
c) Calculate the mean absolute deviation (MAD) of each data set.
12.9, 10.9, 10.9, 9.9, 8.9, 6.9, 2.9, 1.9, 1.9, 0.9, 0.1, 1.1, 3.1, 4.1, 5.1, 6.1, 9.1, 10.1, 11.1, 18.1 / 20; 136/20 = 6.8
The mean absolute deviation (MAD) for each data set is 6.8: Is this correct?
d) Which set is more variable? How do you know?
