Answer 1

Answer: 92

Explanation:

Total number of data (N) = 18.

Median = (N+1)/2 th term

Median = (18+1)/2 th term

Median = 9.5 th term

Now, look at the 9th and 10th term.

9th term = 88

10th term = 96

9.5th term is in between 9th and 10th term, so take mean of these two values

Median = ( 88 + 96 ) / 2

Median = 92

Answer 2

The answer is 88. Median is middle number and you don’t count the same number twice
