Re: GROUPS FOR SIGNIFICANT DIFFERENCES

[Roberto Gil Saura [iO]]

Nowadays, SPSS versions have a test t for differences in contingency tables (personalized tables module) with Chi Square and T test . Use of A / B /C (for identify groups) ... is more general in other software like SPSS, BARBWIN, QUANTUM and other.

I hope PSPP with this feature early.

Thanks.

Un cordial saludo.

I don't know what A and B represent in your example.

Fisher LSD compares the results for each group against those in each other group.
So you get a table of group differences.

you can achieve this with a command similar to

ONEWAY /VARIABLES= yield BY cultivar
     /POSTHOC=LSD.

     The other day I was testing the results of differets cultivars of soya and
     I stucked. The ANOVA said  there are significant differences, so I did a
     LSD FISHER test, to see with more details the differences, but I can't
     generate the table with the discriminated groups.

     I want to generate somethig like this:

     Cultivars                Kg/ha
     Monsanto 32              32    A
     Monsanto 33              52    B
     Don Mario LS             31    A

     (In this case, Monsanto 32 and Don Mario LS didn't show significat
     differences in the yields)

     How I get this?
