Chapter 1:

Mean= (sum of values)/(number of values)

Cumulative frequency= the sum of the frequencies in a class, and all previous classes.

Example: for the second class, the cumulative frequency is 10+30= 40.

Relative frequency: (frequency in a given class)/(total frequency)

Example: The first class listed below has a relative frequency of 30/(10+30+27+18+15)= 0.3

Cumulative relative frequency= the sum of the relative frequencies in a class, and all previous classes.

Example: the cumulative relative frequency for the second class below is 10/100= 0.10, plus 30/100= 0.3; 0.10+0.30= 0.40

Notice that if you know all but one of the quantities for a formula, you can find the remaining one by difference.
