In a school, 100 pupils have heights as tabulate below:
|Height (in cm )||No. of pupils|
Find the median height by drawing an ogive.
|Height (in cm)||No. of pupils||Cumulative Frequency|
Number of terms =100
∴ Median = `100/2=50^(th)` term
Through 50th term mark draw a line parallel to the x-axis which meets the curve at A. from A, draw a perpendicular to x-axis which meets it at B.
Value of B is the median=148
⇒ Median height = 148 cm
