Find the median of first nine even natural numbers.
उत्तर
First nine even natural numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18
Here, n = 9 ......(Odd)
∴ Median = Value of `((n + 1)/2)`th observation
= Value of `((9 + 1)/2)`th observation
= Value of 5th observation
= 10
Hence, the median of first nine even natural numbers is 10.
