For example, if ten students score 90 in statistics, then score 90 has a frequency of 10. All classes should have the same width. The lower class limit of a class is the smallest data value that can go into the class. For example, 10 19 3 20 29 7 30 39 2. Class from the class boundaries statistics calculator, from Excel class limit and add the from. Contact. The solution gives detailed steps on solving 4 descriptive statistics questions. 3. Frequency Distribution Calculator. Frequency can be represented by f. Both of them are the same, they are the contrast between higher and lower boundaries. In that case no other information about the data is needed, only the Min=10 and Max=200. Class boundaries are generally done for continuous variables. For overlapping classification or mutually exclusive classification that excludes the upper class limits like 1. the class boundaries coincide with the class limits.
