The median average of a set of numbers is the middle number when the numbers are listed in order. If there is an even number of numbers then the median is the mean average of the middle two:
There are 2 numbers, therefore the median is the mean average of the middle two, which are the 1st and the 2nd
→ median = (98 + 101) ÷ 2 = 99.5

The median average of a set of numbers is the middle number when the numbers are listed in order. If there is an even number of numbers then the median is the mean average of the middle two. To find which is the median value add 1 to the number of items and divide by 2. If this is a whole number that is the median; otherwise the median is the mean average of the numbers that are at the whole part of this result and the next one: The dataset {95, 95, 98, 98, 98, 101, 102, 103, 104, 104} has 10 items, so the median is the mean average of the middle two. To find which is/are the median value::(10 + 1) /2 = 11/2 = 5.5 → the median is the mean average of the 5th and 6th items. → median = (98 + 101) ÷ 2 = 95.5
98 = 9.8 × 101
Median = 94 but that sure was a weird spelling test!
