A study is being conducted in which a variable of interest has 2,020 observations. The minimum value in the data set is 400 points and the maximum is 2,050 points. (A) Use the 2k ≥ n guideline to determine the minimum number of classes to use in developing a grouped data frequency distribution. Answer (A) : the value of k is k = (B) Based on the answer to part a, determine the class width that should be used. Answer (B) : The width of the class must be points A set of data has values that vary from 30.2 to 97.8. If these values are grouped into eight classes, what class interval width did you choose (round up to tne next integer value)?
