I all, I'm sure I'm being stubid but i need some clarification. The following tables show the scores of two groups of students in a test question. i) Mark 0 1 2 3 4 Frequency 10 5 8 x 3 Determine the value of x if the median of these marks is 1.5 I have a formula for the median when it's odd or even and they don't seem to work n is odd: x= ( xn + x(n+1) )/ 2 Thanks
