Interesting, perhaps, but horrendously undependable and possibly bogus. I checked out several academic job categories for my location and found the reported 25th-, 50th-, and 75th-percentile salaries to be of by HUGE amounts. I tried to click on "About Us," "Contact Us," and "Site Feedback" a

Dear colleagues: I received many responses to my inquiry. Thank you for the constructive feedback. I didn't specify what it meant by "pseudo" normal or approximately normal because, as some of us pointed out, it is impossible to have a standard normal distribution in some cases where the vari

Hi, I don't know R, but once you know how to compute each effect and its significance you should be able to make an Excel sheet in less than 1 hour, plus 1 hour to check if the results of the calculations agree with examples found in textbooks. I've done some 2^n factorial design analysis using e

Dear Chris: For some purposes you can get a close-enough-to-normal from the number of heads in 4 tosses of a fair coin. This distribution (binomial with n=4 and p=.5) takes on 5 values, has mean 2, and SD = 1. If you take X = (# Heads -2), you have a discrete distribution with mean 0, vari
