We know that the median of a given set of observation is the value which divides it into two equal parts.
Given that, the number of observations is 10, which is even.
Arranging the runs in ascending order, we get the following order:
11, 12, 23, 28, 34, 54, 56, 65, 87, 98
Now,
Median =n2th term+(n2+1)th term2
Median =102th term+(102+1)th term2
Median = 5th term + 6th term2
∴Median =34+542=44
Thus, 44 is the median of the runs scored in 10 matches.
