The relative class frequency is the class frequency divided by the total number of observations. Once totaled the relative frequency total should be 100%, but may be off very slightly do the rounding errors. The next step is to draw your histogram placing your class intervals along the horizontal axis and the relative frequency along your ...

relative frequency. of a class is the portion or percent of that data that falls in that class. To find the relative frequency of a class, divide the frequency f by the sample size (sum of all frequencies), n. The . cumulative frequency. of a class is the sum of the frequency for that class and all previous classes.
