If the arithmetic means were used, the safety of the vehicle would be given far more weight, since a small percentage change on a larger scale will result in a larger difference than a large percentage change on a smaller scale; a change of fuel efficiency rating from 2 to 5 which is a 250% increase in rating would be overshadowed by a 6.25% rating change of 80 to 85 if only the arithmetic mean were considered. Continue with Recommended Cookies. Top findanyanswer.com The lower boundary of each class is calculated by subtracting half of the gap value 12=0.5 1 2 = 0.5 from the class lower limit. For example, in the second class, the lower class limit is 20 and the upper class limit is 24. Class Boundaries: In statistics, class boundaries are endpoints used to separate the data into classes or groups. How to find the class width?
