Describe the abstract idea of a sampling distribution and how it reflects the sample to sample variability of a sample statistic or point estimate. Identify the ...

Example 1: The population from which samples are selected is {1,2,3,4,5,6}. This population has a mean of 3.5 and a standard deviation of 1.70783. The next display shows a histogram of the population.

The smaller standard deviation indicates that the chance flucatations in the mean systolic blood pressure are smaller when we have a larger sample size. This implies that we are able to estimate the ...

Just as the shape of histograms depended on sampling ( cf. Statistical tools you need to know and understand in metrology – Law of a phenomenon [FIC 1454]), estimates of the mean and standard ...
