What is the median of 95 95 98 98 98 101 102 103 104 104?
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
Jennys test grades are 93 89 96 and 98 If she wishes to raise her average to 95 what does she need to score on her next test?
She needs a total of 5 x 95 ie 475 over the five tests. She has 376 so far, so she needs 99 in the next test. 93+89+96+98=376 she wishes to raise her average to 95=> 5x95=475 475-376=99

The average is (98+87)/2 = 92.5
