Question

Median is one of the observations in the data if number of observations is ______.

Answer 1

Median is one of the observations in the data if number of observations is odd.

Explanation:

The median is the middle value in a set of data when the data is arranged in ascending or descending order.

• If the number of observations is odd, the median is the middle number and is one of the actual data values.

• If the number of observations is even, the median is the average of the two middle values, and may not be one of the observations.

Example (odd number of observations):

Data: 3, 5, 7

Median = 5  ...(The middle value)

Example (even number of observations):

Data: 3, 5, 7, 9

Median = `(5 + 7)/ 2 = 6`  ...(Not an actual observation)
