There is no gap between the upper boundary of one class and the lower boundary of the next class. The lower class boundary is found by subtracting 0.5 units from the lower class limit and the upper class boundary is found by adding 0.5 units to the upper class limit. Class Mark (Midpoint) The number in the middle of the class. It is found by adding the upper and lower limits

Class width or Class size It is the difference between actual limits of any class. Relative Frequency The frequency divided by the total frequency. This gives the percent of values falling in that class. Cumulative Frequency The number of values less than the upper class boundary for the current class. This is a running total of the frequencies. Cumulative Relative Frequency (Relative Cumulative Frequency) The running total of the relative frequencies or the cumulative frequency divided by the total frequency. Gives the percent of the values which are less than the upper class boundary. Range The difference between the highest and the lowest values in a set....
