Answer 1

Answer:

Answer

A median is the middle number in a sorted list of numbers. To determine the median value in a sequence of numbers, the numbers must first be arranged in value order from lowest to highest. If there is an odd amount of numbers, the median value is the number that is in the middle of the grouped data.

If there is an even amount of numbers in the list, the middle pair must be determined, added together and divided by two to find the median. Formula for median is middle most value.
