Exercise to Practice - Fre Exercise to Practice: Frequency
Distributions Dr. Castro is the dean of the faculty of
administration and wants to determine how much students study in
it. Select a random sample of 30 students and determine the average
number of hours per week each study: 15, 23, 19, 15, 18, 23, 14,
20, 13, 20, 17, 18, 12, 20, 13 , 21, 18, 29, 17, 18, 10, 26, 15,
14, 17, 33, 23, 12, 27 and 16. Note that, based on the data, the
data has already been arranged in intervals of 5 (from 8 to 12
there are 5 values since 8, 9, 10, 11 and 12 are included). The
same with the other values. He performs the calculations applying
the concepts learned in this unit, i.e., absolute, relative,
cumulative frequencies, etc. Notice that the abbreviation for
frequency is f.
