This makes it particularly useful in statistics for skewed distributions or when dealing with data that represents proportional changes. in this response, i’ll explain the concept step by step, provide the formula, and include examples to ensure you grasp it fully. Here's a step by step guide to calculate the geometric mean for grouped data: find the midpoint of each class interval: add the lower and upper limits of each class interval and divide by 2 to get the midpoint. Thus, the geometric mean is the antilog of the weighted mean of the different values of log xi whose weights are their frequencies fi. in case of a continuous or grouped frequency distribution, x is taken to be the value corresponding to the midpoints of the class intervals.
