Hi
You have only single value for each participant in each gruppo and AFAIK you can
not do statistic on single value.
You can check differences among participants
fit<-lm(valor~participantes, data=df2)> fit<-lm(valor~participantes, data=df2)
> anova(fit)
Analysis of Variance Table
Response: valor
Df Sum Sq Mean Sq F value Pr(>F)
participantes 7 5.167 0.7381 0.3163 0.9358
Residuals 16 37.333 2.3333
and in groups
> fit<-lm(valor~grupo, data=df2)
> anova(fit)
Analysis of Variance Table
Response: valor
Df Sum Sq Mean Sq F value Pr(>F)
grupo 2 22.75 11.3750 12.095 0.0003202 ***
Residuals 21 19.75 0.9405
