Finding Median of Grouped Data When Class Intervals Are Not Given

Find the medi...

Question

Find the median for the following frequency table.
Value $12$ $13$ $15$ $19$ $22$ $23$
Frequency $4$ $2$ $4$ $4$ $1$ $5$

Open in App

Solution

Values are already in ascending order
Total frequency= $20$
There are two mid-values $10^{t h}$ & $11^{t h}$ i.e, $15$ and $19$
Median= $\frac{15 + 19}{2} = 17$
