Square root of the difference between the squares

The square root of the difference between the squares of the values times their probability, 4.5, and the square of the expected value or 1.9 squared.

The standard error

The standard error (standard deviation of the sample mean) is equal to the standard deviation of the population mean of x divided by the square root of the number of observations n.

The standard error of the sample mean

The standard deviation of the population mean of x divided by the square root of the number of observations n.

Standard error is estimated

The standard error of the sample is equal to the standard deviation of the sample divided by the square root of the number of observations n, which in this case is 13.63 divided by the square root of 20, or 3.05.

Standard deviation of the sample divided by

The standard deviation of the sample divided by the square root of the number of observations n.
