Using statistical software (R)
Understanding the differences between using statistical software and using RCMDR.
Example of an ANOVA with R and RCMDR.
This video is a textbook example: don't confuse knowing how to use software with knowing how to analyze data. It's designed for you, and I'm sure you'll grasp its underlying principles.
Thank you for your participation and interest, and thank you for the insightful questions.
A big thank you to everyone for your encouraging comments.
See you soon for more live sessions!
Below is the data used (cultivation of a cereal variety according to 3 protocols), which you can copy into an Excel file named cereale.xlsx. This is the file you will then import into RCMDR to perform the ANOVA. You can watch my video "Installing R Commander - Rcmdr - a very user-friendly interface for using R" ( • R Commander - Rcmdr - l'interface convivia... )
(First, copy these lines into a text file, then import the data from that text file into Excel, specifying that the separator is ";" followed by a semicolon.) :
