The following table shows the increase in height of 20 students in a year. Complete the activity to find the median increase in height :

Here, `(N)/(2)=10,cf=2,f=10,h=15.`
Median `=L+[((N)/(2)-cf)/(f)]xxh" "`...... (Formula)
`=1.5+(square-2)/(10)xx1.5`
`=1.5+(square)/(10)xx1.5=1.5+square=square`
The median increase in height is 2.7 cm.
