WebAll other calculations stay the same, including how we calculated the mean. Example: if our 5 dogs are just a sample of a bigger population of dogs, we divide by 4 instead of 5 like this: Sample Variance = 108,520 / 4 = 27,130. Sample Standard Deviation = √27,130 = 165 (to the nearest mm) Think of it as a "correction" when your data is only a ... WebIf we used standard deviation alone, the data would meet the specifications with a value of 0.076-ft. However, looking at the high value of 0.246-ft. (7.5-cm) of the mean, it is obvious this data set contains a bias and the only way to catch it is by either evaluating the value of the mean or using the RMSE as the accuracy measure.
