Question

Here is a list of numbers:
-20, -20, 2, 7, -14, -4, -17, 13, 7
State the median.

Answer 1

-4

Explanation:

To identify the media, you have to:

''Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.''

If we follow the steps, the answer should be -4. With 9 data values, the middle number is the data value at position 5. And position 5 is -4. So the answer will be -4. Hope this helps !

Answer 2

-4

Explanation:

arranging in ascending order

-20,-20,-17,-14,-4,2,7,7,13

number of terms=9

middle term= (n+1)/2=(9+1)/2=5th=-4
