Excel calculates a separate set of statistics for each column or row of your data. If you want to calculate statistics for all of your data, make sure your data is only in one row or column. Excel's output looks like this:

Excel's Function Key

You can use Excel's function key (fx) to calculate some statistics.

However, you may have to perform some preliminary calculations on your own and set up inputs of the calculation in a spreadsheet. For example, if you wanted to calculate confidence intervals for a set of data you would need to perform the following steps:

Calculate n, average, standard deviation and alpha for your data. Input these values into a spreadsheet, then label a cell "Confidence Interval" and click on the fx key to insert a function into the cell formula.

Click okay and define the inputs.
