**R Handbook Transforming Data**

The reason for anchoring the guiding line at the quartiles is really the same reason that boxplots use quartiles for the central chunk. You don't want the guiding line to be influenced by the tails too much. It's a robustness thing. In order for the 45 degree line to be useful, you have to *standardize* your residuals so that they look like *standard* normal... R has functions for quickly producing Q-Q plots; they are qqnorm(), qqline(), and qqplot(). These are good functions to use. I built the above Q-Q plots using more rudimentary functions because These are good functions to use.

My advice is to open R and play along with the tutorial. Hopefully, you have installed R and found the icon on your desktop that looks like an R... well, it is an R. If you're using Linux, then stop looking because it's not there just open a terminal and enter R (or install R Studio.)

- If you are completely ontop of the conceptual issues pertaining to Nested ANOVA, and just need to use this tutorial in order to learn about Nested ANOVA in R, you are invited to skip down to the section on Nested ANOVA in R.
- R also has a qqline() function, which adds a line to your normal QQ plot. This line makes it a lot easier to evaluate whether you see a clear deviation from normality. The closer all points lie to the line, the closer the distribution of your sample comes to the normal distribution. The
