Sylvia received the following scores on 5math exams.87,92,78,92,81 Whay is her median score?

You are kidding right? No way. 78, 81 , 87 92, 92. 87 is the answer. If there was an even set of numbers there... When the numbers in a distribution sample is odd, the median number is the middle number. For instance, the median of 1,4,9 is 4. When there is an even set of numbers, the median is the mean of two middle numbers. Thus the median of the numbers 2,4,9 and 12 are (4+9)/2=6.5. The median along with mean and mode forms an important statistical measure of value.
