Sampling Distribution Models
... We use the sample size to determine the standard deviation for the sampling distribution. Since n is in the denominator of the formula, the bigger the n, the smaller the standard deviation. ...

Mean, Variance, and Standard Deviation
... It is easy to show that the variance is simply the mean squared deviation from the mean. Covariance and Correlation Next, let (X1 , Y1), (X2 , Y2) ,…, (Xn , Yn) be n pairs of values of two random variables X and Y. We wish to measure the degree to which X and Y vary together, as opposed to being ind ...
