back around 1960 ... there appeared via ETS ... a two side nomograph that found (on one side) partial rs ... and (on the other side) multiple Rs ... where you could enter the graphs from 2 or more directions and read these values off ... (if your eyesight was good enough!) the first was by ruth lees and fred lord, the second was from fred lord ... 1. J. Amer. Stat. Assoc, December 1962 2. J. Amer. Stat. Assoc, December 1955 now, back then i assume you could get these from ets ... i would be SHOCKED if you could "buy" or "get" this nomograph anymore ... to show how creative some folks were to help "users of stats" figure out things ... i have scanned this and you can see at http://roberts.ed.psu.edu/users/droberts/multr.jpg http://roberts.ed.psu.edu/users/droberts/partr.jpg if you have a look and think of the WORK it took on SOMEone's part to draw these back then ... my hat's off to them!!!! NOW, IF ANYONE THINKS I SHOULD NOT POST THESE ... LET ME KNOW AND I WILL YANK THEM OFF THE SERVER RIGHT AWAY ... i just thought this was interesting in light of the post i sent re: normal curve template _________________________________________________________ dennis roberts, educational psychology, penn state university 208 cedar, AC 8148632401, mailto:[EMAIL PROTECTED] http://roberts.ed.psu.edu/users/droberts/drober~1.htm ================================================================= Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =================================================================
