WebThe formula to find class mark is given as, Class mark = (upper limit + lower limit)/2, or (sum of class boundaries)/2. For example, to find the class mark of the interval 25-30, we add these values which give us 25 + 30 = 55. Now we divide it by 2 to find the average. This implies, 55/2 = 27.5. So, 27.5 is the class mark of 25 - 30. WebThe class interval represents the distance between a given class' lower class limit and the lower class limit of the next class. As described above, all the class intervals within a …
