Solution
since the class marks are uniformly spread.
therefore the class size is the difference between any two consecutive class marks.
class size = 26.5 - 19.5 = 7
since the class marks are uniformly spread.
therefore the class size is the difference between any two consecutive class marks.
class size = 26.5 - 19.5 = 7
