Description:
Welcome to the series of tutorials on Two-way ANOVA with R.
In this series of videos, we are going to perform a complete analysis of a two-factor factorial design.
We are going to cover the following steps :
Video tutorial 1 (   • Two-Way ANOVA with R - Analysis of Va...  ):
build a simple plot for data visualisation;
perform the analysis of variance;
Video tutorial 2 (   • Tukey's Test and Letters to Indicate ...  ):
create a table with the mean and standard deviation of each treatment;
compare the means by Tukey’s test;
use the compact letter display to indicate significant differences;
Video tutorial 3:
build a high-quality publication-grade bar plot,
letters indicating significant differences
grey-scale and colour-blind friendly
