... Note: x forms the basis of the interval. The margin of error is subtracted from it, and then added to it. For sample means when the population standard deviation is not known, the distribution follows a t-distribution. It is bell-shaped and behaves like the normal distribution, but changes based on ...

Sample and Population Variance
... For the data in this example, it is known that the population variance, σ2, is 16. So to be an unbiased estimate of this population variance, we expect the value of the sample variance to be s2 = 16. That is, the average value of the variance (i.e. the average of all the data points in the dot plot ...
