But seemingly non of them can explain to me following output:- > tabA = c(5.67, 5.67, 5.55, 5.57) > tabB = c(5.75, 5.47, 5.43, 5.45) > tabC = c(4.74, 4.45, 4.65, 4.94) > tabs = data.frame(tabA, tabB, tabC) > tablets = stack(tabs) > anova(lm(values ~ ind, data = tablets)) Analysis of Variance Table Response: values Df Sum Sq Mean Sq F value Pr(>F) ind 2 2.05787 1.02893 45.239 2.015e-05 *** Residuals 9 0.20470 0.02274 --- Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 > TukeyHSD(aov(values ~ ind, data = tablets)) Tukey multiple comparisons of means 95% family-wise confidence level Fit: aov(formula = values ~ ind, data = tablets) $ind diff lwr upr p adj tabB-tabA -0.09 -0.3877412 0.2077412 0.6866791 tabC-tabA -0.92 -1.2177412 -0.6222588 0.0000321 tabC-tabB -0.83 -1.1277412 -0.5322588 0.0000731 Please help.
