Frequency is the number of times a response is given. A relative frequency compares the given responses to the overall respondents of a survey or group. A detailed example follows. The cumulative relative frequency is calculated in a running total by adding 13/50 to 20/50, 8/50 and 9/50 for a total of 50/50. The decimal calculations are 0.26 added to 0.40, 0.16 and 0.18 to equal one. A running total of the cumulative relative frequency is listed as 0.26, 0.66, 0.82 and then finally one.
