used when the range is large and classes several units in width are needed ungrouped frequency distribution used for numerical data and when range of data is small; each class is only one unit
frequency distribution (guidelines for constructing) 1. decide on the number of classes. this will be given in each problem. 2. find the class widths. class width =range/number of classes. always round up to the nearest whole number( EX: 2.8 rounds up to 3. 2.3 also rounds up to 3) 3. find the class limits. use the minimum as the starting value of the first class. then add the class width to the minimum of the previous class. this will give you the lower limits for the next class. then, you can easily find the upper limits by the class width. classes canNOT overlap.
