Find the median of the numbers 9,7, 5, 2, 12,9,9, 2, 10, 10, and 18.
Answer Details
To find the median of a set of numbers, we need to arrange the numbers in order from least to greatest.
Arranging the given set of numbers in order, we get:
2, 2, 5, 7, 9, 9, 9, 10, 10, 12, 18
There are 11 numbers in the set. Since 11 is an odd number, the median is the middle number when the set is arranged in order.
The middle number is the sixth number, which is 9.
Therefore, the median of the set of numbers 9, 7, 5, 2, 12, 9, 9, 2, 10, 10, and 18 is 9.
