Two Way ANOVA | Coding Method (Subtracting 40) | VTU Maths

🎓 Two Way ANOVA | Coding Method (Subtracting 40) | Exam Problem

In this video, we solve a Two Way ANOVA problem using the coding method, where 40 is subtracted from all given observations to simplify calculations. This technique is commonly used in VTU and university examinations to reduce arithmetic effort while constructing the ANOVA table.
The data involves pieces of land and four different treatments, and we are required to set up the complete Two Way ANOVA table using the coded values.
