# A football player scored the following number of goals in the 10 matches :

1, 3, 2, 5, 8, 6, 1, 4, 7, 9

Since the number of matches is 10 (an even number), therefore, the median

= (5th observation + 6th observation)/2

= (8 + 6)/2 = 7

Is it the correct answer and why?

**Solution:**

The given data is

1, 3, 2, 5, 8, 6, 1, 4, 7, 9

By arranging it

1, 1, 2, 3, 4, 5, 6, 7, 8, 9

Number of observations is 10 which is __even__

__Median__ = (n/2)th observation + (n/2 + 1)th observation/2

Substituting the values

Median = (10/2)th observation + (10/2 + 1)th observation/2

Median = (5th observation + 6th observation)/2

Median = (4 + 5)/2

So we get

Median = 9/2

Median = 4.5

Therefore, 7 is not the correct answer as the data has to be arranged in __ascending__ or descending order before determining the median.

**✦ Try This: **A football player scored the following number of goals in the 10 matches: 2, 5, 1, 7, 6, 2, 4,

Since the number of matches is 8 (an even number), therefore, the median

= (3rd observation + 4th observation)/2

= (1 + 7)/2 = 4

Is it the correct answer and why?
