## Important Definitions RD‌ ‌Sharma‌ ‌Chapter‌ ‌24 ‌Class‌ ‌9‌ ‌Maths‌ Exercise‌ ‌24.3 ‌Solutions‌

This exercise is based on the topics-

1. Median
2. Median of an ungrouped data

### Median

Median is considered the middle figure in a set of numbers, be it in sorted, increasing, or decreasing order. These numbers can be a way lot elaborative of the set of data compared to average. When the amount of numbers present is odd, the median value is the number that remains there in the middle, having an equivalent amount of numbers remaining under and above.

### Median of an ungrouped data

The Median of ungrouped data can be defined both for even and odd numbers. In fact, the formula differs for even and odd.

When n is odd, the Median of ungrouped data becomes-

Median = [(n+1)/2]th observation

When n is even, the Median of ungrouped data becomes

Median = mean of (n/2)th observation and [(n/2)+1]th observation, if n is even.
