Harmonic Mean (H.M) - Definition, Formula, Derivation, …

WebThe harmonic mean has the following merits. It is rigidly defined. It is based on all the observations of a series i.e. it cannot be calculated ignoring any item of a series. It is … WebFor ungrouped data, we can easily find the arithmetic mean by adding all the given values in a data set and dividing it by a number of values. Mean, x̄ = Sum of all values/Number of values. Example: Find the arithmetic mean of 4, 8, 12, 16, 20. Solution: Given, 4, 8, 12, 16, 20 is the set of values. Sum of values = 4+ 8+12+16+20 = 60. basal marker

It focuses on all the views of a set, i.e., no object of a series can be computed without it. It supports the algebraic approach. It produces a more consistent outcome if the outcomes in question are the same using the different methods to compute the mean. WebAnother advantage of the harmonic mean is that it is less sensitive to outliers than the arithmetic mean. This means that if there are a few extreme values in the set of … basal lung atelectasis
