[nabs-l] Locating a standard normal distribution table

Thu Feb 16 16:41:25 UTC 2012

Excel will compute z tests, t tests, and r values or correlation coefficients. I always had to enter the syntax of the formulas. I've never been able to select and fill in formulas from the menus, but syntax can  be googled.
