Subtract the result from the lower class limit and add the result to the the upper class limit for each class. 2. Class boundaries are the numbers used to separate classes. 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. 6.

Classmark in statistics To group the data, the following steps must be followed: Determine the range or path of the data Range = Higher value - Lower value Set the number of classes (K) In order to establish the number of classes where the data will be grouped, it is necessary to have a base such as the ones that can be seen in the following table. Class boundaries are the end points of an open interval which contains the class interval such that the lower class boundary (LCB) is the LCL minus one-half the tolerance and the upper class boundary (UCB) is the UCL plus one-half the tolerance. Instructions : This descriptive statistics calculator for grouped data calculates the sample mean, variance and standard deviation for grouped data. the class boundaries coincide with the class limits. The equation for calculating the geometric mean is as follows: In the equation above, i is the index that refers to the location of a value in a set, xi is an individual value, and N is the total number of values.
