उत्तर
Median of the following numbers: 4, 4, 5, 7, 6, 7, 7, 12, 3 is 6.
Explanation:
First, we arrange the given numbers in ascending order is 3, 4, 4, 5, 6, 7, 7, 7 and 12.
Here, n = 9
Since, n is odd, so we use the formula for median.
Now, median = `((n + 1)/2)`th observation
= `((9 + 1)/2)`th observation ...[Put n = 9]
= `(10/2)`th observation
= 5th observation
= 6
Hence, median of the given number is 6.
