In Excel, what is the function that tests for statistically significant
differences between two percentages?

You need a larger sample than 2 to arrive at a statistically significant
difference. To that end you can use Standard Deviation (StdDev) and see which
items deviate significantly from the average...

My apologies, I was not clear. How do I test for differences between two
percentages which are averages? Say, two sets of data, test scores, I want
to test the average percentage for test 1 to the average percentage for test
2. So, if I have the averages for the two percentages, and the size of each
sample (in this example, the number of test scores for tests 1 and 2,
respectively), I should be able to test for sig. differences. How does one
do this in Excel? (I've done it in another statistical program.)
