The box and whisker plot drawn below makes this comparison even clearer. The p-value (cell K13) is zero, so we can reject the null hypothesis that the means are equal (means are not different). Here is the output of an ANOVA Single Factor test that was run using QI Macros: Box-Whisker-Plot Ein vertikaler Boxplot ber einem Zahlenstrahl dargestellt Der Boxplot (auch Box Whisker Plot oder.
