Question

The mode and median of the following data $21,23,25,23,21,24,22,20,23$ respectively, are

• A. $23,23$
• B. $21,23$
• C. $25,21$
• D. $23,21$

Answer 1

The correct option is A $23,23$

Given data is $21,23,25,23,21,24,22,20,23$

Here $23$ occurs more frequently.
Thus mode $=23$
On arranging ascending order, we get
$20,21,21,22,23,23,23,24,25$
Total number of terms $=9$
Therefore, median $=$ ${\left(\frac{9+1}{2}\right)}^{th}$ term $=5^{th}$ term $=23$.
