Tip 45: Using the AGGREGATE Function
Figure 45-2 shows an example of how the AGGREGATE function can be useful. The worksheet
contains pre-test and post-scores for eight students. Note that Charles did not take the post-test, so cells
C4 and D4 contain the NA/# error value (to indicate not available).
Cell D11 contains a formula that uses the AVERAGE function to calculate the average change. This
formula returns an error:
=AVERAGE(D2:D9)
The formula in cell D12 uses the AGGREGATE function, with the option to ignore error values:
=AGGREGATE(1,6,D2:D9)

Remember that AGGREGATE works only with Excel 2010 and later. If a workbook that uses this
function is opened in a previous version of Excel, the formula will display an error.
