count how many numbers there are in the leaf column = 6+5+6+3 + 2 = 22 so counting from left to right and top to bottom find the 11th and 12th value and find the mean of these 2

OpenStudy (cwrw238):

as i said find the 11th and 12th numbers the median is the mean of these 2 numbers hint: 11th number is 28 do you see why?
