Does anybody know how to get mean and standard deviation from
CrickGraph? You can do Z-scores which CricketGraph defines as (X - Mean) /
Standard_Deviation; it obviously calculates the mean and s.d. but the damn
program won't let you see them!
What I really want to do is this: I've got some data sets with
several observations of Y for each X. I'd like to take the data in the
first 4 columns below and generate (as opposed to calculating myself and
entering) the last 2 columns, then do a line plot of X vs. Yavg using sd-Y
for Y error bars.
X Y1 Y2 Y3 Yavg sd-Y
1 10 10 12 10.67 1.155
2 20 25 22 22.33 2.517
3 31 32 30 31.00 1.000
A similarly useful thing to do would be to get the range of the Ys
and use that for the error bars. Should I break down and admit that this
is out of CricketGraph's league and get a real spreadsheet? Another useful
thing would be to have non-symmetric error bars (as in "IBM closed at 14-1/2
with a high of 14-7/8 and a low of 14-3/8"). Any way to make CricketGraph
do that?

TS GRaph does what you want to do. This is a superior graphing program to Cricket in many ways, and the last time I checked, only cost $15. Try calling BAKA industries at 607/257-2070, a local mac shop that is carrying TS Graph. Or send me mail if you have other questions. >-- >Roy Smith, System Administrator >Public Health Research Institute >455 First Avenue, New York, NY 10016 >{allegra,philabs,cmcl2,rutgers}!phri!roy -or- phri!roy@uunet.uu.net Ron Beloin, Ecosystems Research Center, Corson Hall, Cornell, Ithaca,NY 14853 >> opinions << BITNET:BELOIN@CRNLTHRY; INTERNET:beloin@tcgould.tn.cornell.edu >> are mine << UUCP:{cmcl2,shasta,uw-beaver,rochester}!cornell!tcgould!beloin
