Sampling distribution of the sample range
WebDec 21, 2014 · Depends on the variance of your estimator for the sample variance. With 100 data points, you may find something like 4.92. With 1000, you'll find something like 4.98. WIth 10000, you'll find 5.0001. So is the accuracy of your measurements that increases, not your measurements themselves. – Ant Oct 17, 2024 at 21:19 Add a comment 6 Answers WebRemeber, The mean is the mean of one sample and μX is the average, or center, of both X (The original distribution) and . We can use our Z table and standardize just as we are already familiar with, or can use your technology of choice. An unknown distribution has a mean of 90 and a standard deviation of 15.
