The median of the data : 3, 4, 5, 6, 7, 3, 4 is
(a) 5
(b) 3
(c) 4
(d) 6

Solution:

Given, the data is 3, 4, 5, 6, 7, 3, 4

We have to find the median of the given data.

When the given data is arranged in ascending (or descending) order, then the middle most observation is the median of the data.

Arranging the data in ascending order, we get

3, 3, 4, 4, 5, 6, 7

Number of observations, n = 7

If n is odd, then median = (n+1)/2 th term

Median = (7+1)/2 th term

= 8/2 th term

= 4th term

4th term = 4

Therefore, the median is 4.
