Hi ElMaestro,

» I do not have Excel, but it sounds like an embarrassing implementation.

I guess that I shouldn't be surprised given its history...

» Can you try, just for the fun of it, to ask Excel what it thinks the critical value at df=10.1 is for:
»
» a. p=0.9994425014527133
» b. p=0.999428447456598

Good idea.
T.INV(0.999442501452713, 10.1) = 4.51612251417097
T.INV(0.999428447456598, 10.1) = 4.50000000000000

In fact, I just checked that T.DIST(4.5, df, TRUE) will give exactly the same result for df = 10.1, 10.2, ... 10.9, (increase df but let df < 11). The result only changed when df = 11!

Nice work, M$.

All the best,
