Answer 2

Answer:

1 is the median

Step-by-step explanation:

If the number of observations is odd, the number in the middle of the list is the median. This can be found by taking the value of the (n+1)/2 th term, where n is the number of observations. Else, if the number of observations is even, then the median is the simple average of the middle two numbers.
