Answer: 92
Step-by-step 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
The answer is 88. Median is middle number and you don’t count the same number twice
