A football player scored the following number of goals in the `10` matches `1,3,2,5,8,6,1,4,7 `and `9.` Since, the number of matches is `10` (an even number), therefore
Median `=(5^(th) "observation"+6^(th) "observation")/2=(8+6)/2=7`
Is it the correct answer and why?

Explanation

No, it is the correct answer, because the data have to be arranged in ascending or descending order before finding the median.
Arranging the data is ascending order `1,1,2,3,4,5,6,7,8,9.`
Here, number of observations is 10, which is even.
So, median=`((n/2th) "observation"+(n/2+1) "observation")/(2)`
`((10/2)th "Observation"+(10/2+1)th "Observation")/(2)`
`(5th "observation"+6th "Observation")/2=(4+5)/2=9/2=4.5`
