I wonder if anyone on this forum knows how to calculate using EXCEL the statistics for "difference in differences".

I have 4 sets of groups -
each group has a mean and a standard error
I am trying to calculate if the difference between group 1 and 2 is the same or not the same (statistically) from the difference between group 3 and group 4.

I can do student t, but not sure what statistics to use in EXCEL to calculate the difference in differences.

Any help?

Is there a shortcut key for strikethrough?
Ctrl+S is used for Save. Ctrl+5 is used for Strikethrough. Why Ctrl+5? When you use hashmarks to count |||| is 4, strike through to mean 5.
You can do an ANOVA in excel if thats what you mean. That will tell you if your groups are the same statistically.

Don't think ANOVA is applicable.
ANOVA can tell me if there are differences in the 4 groups.
But I need to get two numbers first - the difference in group 1 and 2. and the difference in group 3 and 4. (say height between group 1 and 2 and height between group 3 and 4).
Then I ask if the height difference between group 1 and 2 is different or not (statistically) from the height difference between group 3 and 4.

You could perform an ANOVA on the differences. Why you would use differences and not just the heights themselves?
