Hey all,

I have this output from a repeated measures ANOVA:

repeatedmeasures=aov(data=ProportionofCorrectTrials, Proportionofcorrecttrials ~ Condition

Firsttargetboundary + Error(ID/ (ConditionFirsttargetboundary)))

summary(repeatedmeasures)

Error: ID

Df Sum Sq Mean Sq F value Pr(>F)

Residuals 12 1.341 0.1117

## Error: ID:Condition

Df Sum Sq Mean Sq F value Pr(>F)

Condition 2 0.5474 0.2737 6.644 0.00506 **

Residuals 24 0.9888 0.0412

Signif. codes: 0 ‘* ’ 0.001 ‘’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1

Residuals 12 0.3689 0.0307

Condition:Firsttargetboundary 2 0.0320 0.01598 0.867 0.433

Residuals 24 0.4423 0.01843

Error: Within

Df Sum Sq Mean Sq F value Pr(>F)

Residuals 162 4.921 0.03037

I then tried to create a normality plot:

resid <- aov.out.pr[[3]][,"Residuals"]

qqnorm(resid)

qqline(resid)

I am able to create the plot successfully, but I would be grateful if one could reassure me as to whether this is the right way to do it?
