Question
The following data represent exam scores in a statistics class taught using traditional lecture and a class taught using
a "flipped" classroom. Complete parts (a) through (c) below.
Traditional
Flipped
81.1 70.5 63.0 70.2 59.8
70.4 68.7 79.7 68.3 85.1
80.7
77.2 71.4 63.4
76.0 83.0 70.1 91.3 78.7 77.2
78.0 56.5
(a) Which course has more dispersion in exam scores using the range as the measure of dispersion?
The traditional course has a range of while the "flipped" course has a range of The
more dispersion.
(Type integers or decimals. Do not round.)
73.3 78.3 90.5 79.6
(b) Which course has more dispersion in exam scores using the sample standard deviation as the measure
of dispersion?
The range is now
(Type an integer or a decimal. Do not round.)
How does this affect the standard deviation?
The traditional course has a standard deviation of, while the "flipped" course has a standard deviation of
course has more dispersion.
(Round to three decimal places as needed.)
The standard deviation is now
(Round to three decimal places as needed.)
What property does this illustrate?
