Part 2: sorting the data. step 2: subtract the minimum data value from the maximum data value. for example, our iq list above had a minimum value of 118 and a maximum value of 154, so: 154 – 118 = 36. step 3: divide your answer in step 2 by the number of classes you chose in step 1. R = 68 11 = 57 step (2) decide the approximate number of classes: must be between 5 and 20 sturges formula k=1 3.322 log n=[1 (3.322) (log n) determine the approximate class interval size (c): the size of class interval is obtained by dividing the range of data by number of classes. c= r k = 57 7 = 8.143 ≈ 8 before we continue to the next. To construct a frequency table: 1) first sort the data into classes 2) count the number in each class and report as the class frequency 3) convert each frequency to a relative frequency 4) each of the class frequencies is divided by the total number of observations 5) shows the fraction of the total number observations in each class.

Organize data into a bar chart. lo 2 3: present a set of data using pie chart. lo 2 4: create a frequency distribution for a data set. lo 2 5: understand a relative frequency distribution. lo 2 6: present data from a frequency distribution in a histogram or frequency polygon. lo 2 7: construct and interpret a cumulative frequency distribution. Constructing a frequency distribution. step 1: decide on the number of classes. a useful recipe to determine the number of classes (k) is the “2 to the k rule.”. such that 2k > n. there were 80 vehicles sold. so n = 80. if we try k = 6, which means we would use 6 classes, then 26 = 64, somewhat less than 80. hence, 6 is not enough classes.
