Take two perpendicular lines OX and OY on the squared paper and graduate them with divisions as needed by the data. Represent the below data on the squared paper. Height Less than b Less than c Less than d Less than e Less than f Cumulative frequency f 1 f 1 + f 2 say F 1 f 1 + f 2 + f 3 say F 2 f 1 + f 2 + f 3 + f 4 say F 3 f 1 + f 2 + f 3 + f 4 + f 5 say F 4

Graph showing the Cumulative frequencies vs Intervals. OX is the x -axis. OY is the y -axis.

Take two perpendicular lines $OX$ and $OY$ on the squared paper and graduate them with divisions as needed by the data.

Represent the below data on the squared paper.

Height	Less than $b$	Less than $c$	Less than $d$	Less than $e$	Less than $f$
Cumulative frequency	$f_{1}$	$f_{1} + f_{2} (say F_{1})$	$f_{1} + f_{2} + f_{3} (say F_{2})$	$f_{1} + f_{2} + f_{3} + f_{4} (say F_{3})$	$f_{1} + f_{2} + f_{3} + f_{4} + f_{5} (say F_{4})$
