The relative frequency of students working 9 hours or less c. is 39, which is: the largest value minus the smallest value or 39 - 0 = 39 c. 30 - 39 The relative frequency can be calculated using the formula fi=fn f i = f n , where f is the absolute frequency and n is the sum of all frequencies. a. relative Then create a tally to show the frequency (or relative frequency) of the data into each interval. 1, there are three students who work two hours, five students who work three hours, and so on. Refer to Exhibit 2-4. .50 c. dividing the frequency of the class by n c. 2% QUESTIONThe relative frequency of a class is computed byANSWERA.) I think it has to do with whether they ask for the row relative frequencies, or the column relative frequencies. 1 37. The data is summarized in the following table: 22. The result is then expressed as either a fraction or a percentage. asked by Tykrane. b. In a relative frequency distribution, the number assigned to this class would be 0.25 (50/200). Histogram The number of students who work 19 hours or less is 100 Cumulative frequency begins at 0 and adds up the frequencies as you move through your list. Alan received his PhD in economics from Fordham University, and an M.S. An Ogive is constructed by plotting a point corresponding to the ___ frequency of each class. The relative frequency of each class is the proportion of the data that falls in that class. The numbers of hours worked (per week) by 400 statistics students are shown below. b. relative frequency distribution It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. The relative frequency of the first class would be 3/10, or 30%.
