The height of 50 girls of class X of a school are recorded as follows:

Height (in cm) 135−140 140−145 145−150 150−155 155−160 160−165

Number of girls 5 8 9 12 14 2

Solution

The frequency distribution table of more than type is as follows:

Height (in cm) (lower class limits) Cumulative frequency (cf)

More than 135 5 + 45 = 50

More than 140 8 + 37 = 45

More than 145 9 + 28 = 37

More than 150 12 + 16 = 28

More than 155 14 + 2 = 16

More than 160 2

Taking the lower class limits on x−axis and their respective cumulative frequencies on y−axis, its ogive can be obtained as follows:
