Question

please tell me the answer​

Answer 1

Answer:

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. In calculation, the median is the simple average of the n/2 -th and the (n/2 + 1) -th terms.

Answer 2

hope this help

Step-by-step explanation:

the median of 3, 3, 5, 9, 11 is 5. If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values: so the median of 3, 5, 7, 9 is (5+7)/2 = 6.
