Sampling Fluctuation - David Lane

WebFluctuation in sample: Every sample is different as we are selecting only a few units from the entire population for the purpose of some study. So the statistics (mean, median, mode, s.d. etc) from one sample will differ from that of other sample. This variation is known as Fluctuation in sample. WebApr 11, 2024 · Even if there is a sample fluctuation, the harmonic mean does not get significantly affected. Basically, it is least affected by fluctuation in sampling. All items of the series are required to determine the harmonic mean. It is based on all observations. It gives greater importance to small items. It is capable of further algebraic treatment. 2. dauntless top tier weaponshttp://jiwaji.edu/pdf/ecourse/political_science/MBA%20HRD%20II%20SEM%20246%20chi%20square-converted.pdf dauntless tonics
