I agree with all these comments. One additional point; I always use the table to point out that as N approaches infinity, the t distribution approaches normality (since I’ve already hammered on z=1.96 for a two-tailed normal distribution cut off of .05).

Understand the distribution. If preceded by normal distribution, generalize from that to distribution that is more spread out because SD is varying as well as numerator; also varies with df. Then use table to determine critical values with associated ps. Finally, p values from printout.

So - understanding first, table second and printout third. But of course, after you understand, the printout is all you need. Stuart -----Original Message----- From: Frigo, Lenore [mailto:lfr...@shastacollege.edu<mailto:lfr...@shastacollege.edu>] Sent: April-07-17 8:43 PM To: Teaching in the Psychological Sciences (TIPS) Subject: [tips] Teaching stats and Critical Values Tables For those of you who teach lower-division introduction to research methods (or have an opinion on what we SHOULD be teaching at that level): In teaching students how to interpret statistical results, such as a t-test, do you think it's important to have them find the critical value on a table and proceed from there, or just start with a "print out" of the results that would already include the actual p value? Currently I have them work with the table, but it seems old-fashioned and unnecessarily cumbersome. On the other hand, using the table forces them to perhaps have a bit more conceptual understanding of what they are doing.
