As we learned 

 

Cumulative relative frequency distribution -

The cumulative relative frequency of any value is similarly defined as the relative frequency of the value plus the relative frequencies of all smaller values.

ex :                 x                 1/N=fr                      c.r.f

                      0                  0.08                        0.08

                      1                  0.16                        0.24

                      2                  0.16                        0.40

                      3                  0.24                        0.64 

-

 

 width=\frac{22-7}{5}=\frac{15}{5}=3
