Next, we divide the result by 2. We find the class boundaries, midpoints, and widths for each class using the below formulae: The class boundaries should have one additional place value and end in a 5. It is one-half the sum of the upper limit of one class and the lower limit of the class that immediately comes after it. To find the upper limit of the first class, subtract one from the lower limit of the second class. Given a frequency distribution of some data, for a class boundary x, the cumulative frequency is the sum of all the class frequenies less or equal to x. In statistics the class boundaries are numbers that separate classes without forming gaps. So, we get 1/2 =. x. It comes with ranges of values associated with a frequency. Data Label: First lower class limit: Class width: Number of classes: For class boundaries, use: Width: Height: Class Frequency; 0 x < 3: 3 x < 6: 6 x < 9: 9 x < 12: 12 x < 15 .
