Using Microsoft Excel for Probability and Statistics
... AVERAGE() is only one of a large number of functions which Excel provides to assist with the manipulation of numbers. It is often difficult to remember the precise name of a particular function, or the order of the parameters. To assist you in this, Excel provides the function wizard. If you press t ...

The meaning of Standard Errors
... The mean of a larger sample will tend to be closer to the mean of the population than the mean of a smaller sample. This observation is an important step to a more precise understanding of why the mean of a larger sample is ‘better’ than the mean of a smaller sample. It is more precise because we ar ...

... Without trying to prolong this section too much, we note the transition to a large sample approximation, which results in somewhat simpler formulas, and allows you to use the standard normal probability table instead of the 2 table. Formula (OV-3) is valid for all values of greater than or equal ...
