I'm reading a paper on multiple comparisons (citation below). The paper reports (page 324, step 5) that we need to:
"Find the percentage point of the studentized range (SR_n) corresponding to a and n (the number of samples) and for infinite degrees of freedom."
a = alpha = 0.05
n = number of samples = 5 (in this example in the paper)
The paper then reports that this value is 2.73.
When I look up the table (here, alpha=0.05, df=inf, k=5), I find 3.858
Naturally, these values are quite different and I don't think it's due to my using a table developed in the 21st century vs. the author's 1954 source.
Question: Why is my value (3.858) different from the reported value in the paper (2.73)? How did the author find this value?
