Why do you think that the algorithms in these computer packages =
differ?
Why aren't they universal?
Any thoughts or comments?

I agree with Nat that 38, the median of the lower half, is the first=20
quartile. I have heard about computer packages giving different =
answers=20
before. For example, Excel (the least trustworthy for statistics) =
says=20
38.75! Got me how the packages come up with these.

Actually you are wrong.
Excel uses Gumbel's method. This is one of many accepted methods.
Are you accusing Gumbel that he is wrong?
