traditional 70.3 68.5 79.9 67.6 85.4 79.1 56.0 80.4 79.8 71.7 63.1 70.4 59.1
flipped 75.5 71.7 63.5 71.4 77.7 92.4 79.6 77.5 83.0 69.2 92.6 78.0 76.9
(a) which course has more dispersion in exam scores using the range as the measure of dispersion'?
(b) which course has more dispersion in exam scores using the sample standard deviation as the measure of dispersion?
(c) suppose the score of 59.1 in the traditional course was incorrectly recorded as 591. how does this affect the range?
(d) what property does this illustrate? a. the standard deviation is resistant, but the range is not resistant. b. the range is resistant, but the standard deviation is not resistant. c. both the range and the standard deviation are resistant. d. neither the range nor the standard deviation is resistant.
