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 70.9 68.2 78.7 66.7 84.6 77.7 56.4 80.4 81.9 71.2 64.6 69.0 59.8 Flipped 75.5 70.9 64.4 72.4 78.0 92.8 78.6 77.4 82.7 69.6 92.1 78.0 75.9 ..... (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 course has more dispersion. (Type integers or decimals. Do not round.) (b) Which course has more dispersion in exam sco of dispersion? using the sample standard deviation as the measure The traditional course has a standard deviation of , while the "flipped" course has a standard deviation of |. The course has more dispersion. (Round to three decimal places as needed.) (c) Suppose the score of 59.8 in the traditional course was incorrectly recorded as 598. How does this affect the range? The range is now (Type an integer or a decimal. Do not round.) How does this affect the standard deviation? The standard deviation is now. (Round to three decimal places as needed.)
