We can show this with the original books read table from the beginning of this page. Class Frequencyf Cumulative Frequency 1217 3 3 1823 6 36 2429 4 364 3035 2 3 642 Class Frequency f Cumulative. Then P M M 03 so P M M 07.
Since you have 200 students you need to read from the horizontal line 200 07 140 and find the corresponding value of M from the curve.
Cumulative frequency Relative frequency Cumulative relative frequency Cumulative frequency You add the frequencies up to and including for the value Relative frequency You express the frequency as a fraction or percentage of total sum of frequencies Cumulative relative. If you are just asked for frequency from the relative frequency it probably means the absolute frequency. A cumulative frequency table is slightly different from a standard frequency table. Steps to make a cumulative frequency graph are.
