Analysis of Variance (ANOVA) in R

[@HealthGIS]

19:28 Correction: The test is NOT significant at 99% confidence level since P-value > 0.01

[@berhanuejara5870]

P-value>0.05 accepts (Ha)~rejecting equality of means (H0)! I think you were right

[@avex0118]

Should not we start with verifying the equality of variance first before preeceding to ANOVA ??

This tutorial saved my life. Bless you 🙏🙏

I have An assignement same as this one but i don't know if I need to perform a normality first before moving on to ANOVA. do we need to check the assumptions and how ?

[@marlenethaitumu8177]

Amazing work. Clearly explained!!!

Does anyone know how I would do a very similar ANOVA but with data collected from 6 groups at 12 different timepoints? (i.e. plant height in 6 treatments; 3 plants per treatment, collected at 13 time points)

[@RafaelAlfonsoRiveraReynaud]

I have a question, one of the assumptions of ANOVA is normality in the data or normality in the residuals?

[@avex0118]

did you know the answer?

[@puterizulaikha6528]

What if it has four variables, how the ANOVA ?

[@HealthGIS]

Sorry for the late response.
It doesn't matter. You can use ANOVA to compare the means of two or MORE groups.

Could I have your email and document for self learning ?
