And if you calculate the means of various samples, those means will differ. In other words, the sample mean is a random variable. As such, it has a distribution. ... 7.2 Sampling Distribution of the ...

This web calculator allows users to specify the mean and standard deviation (SD) of the normal distribution, and choose a desired ... the sampling distribution of the sample means is shown. This ...

We can use our sample's mean (5.48) and variance (55.3) to calculate VMR = 10.1, but because we don't have access to the sampling distribution, we don't know the uncertainty.

The sample contains five observations and consists of values $10,000, $100,000, $50,000, $45,000, and $35,000. First, the user needs to create an array called "data" containing these observations ...
