Alan Anderson, PhD is a teacher of finance, economics, statistics, and math at Fordham and Fairfield universities as well as at Manhattanville and Purchase colleges. a. For example, you calculate the relative frequency of prices between $3.50 and $3.74 as 6/20 to get 0.30 (30 percent). Many statisticians have identified the problem [5,6,7,8,9] but the problem remains and is . If you are just asked for "frequency," from the relative frequency, it probably means the absolute frequency. 6.
