Very well explained, it one of the most comprehensive tutorial for Data transformation. I've been trying to understand data transformation for long time but was not able to get complete picture or understand about the lambda function very well from the litareture i found. But this video cleared most of my doubts and helped me alot.

Thank you for this clear video, I have a concern though, how should I interpret data in discussion section ? Should I use original or transformed data ? Ex: monthly average energy comsumption was 560 mega Watt or should I say : 0,00456 mega Something ? Thanks for your feedback

While interpreting the results, you need to interpret w.r.t. Transformation, but the conclusion needs to express w.r.t. original values.

Thank you so much, that was very helpful! I wanted to do a Box Cox Transformation to meet the assumptions for my mixed ANOVA. There are two dependent variables included (Pre and Post experimental measurement). I was wondering which one I have to transform (Or both?) before conducting the ANOVA?

You're so welcome! Glad it was useful. Are both of your data follows the Nonnormal distribution or you can't see the relationship between them? Can you please help me to understand why do you want to transform data?

Could you please help me with the references that support the statement that " in Regression analysis, it is not necessary to correct non-normality". FYI, I am in the middle of writing a dissertation, and data is not normally distributed in my regression model analysis. Regards from Indonesia

In which condition data transformation is needed. (1) Y- continuous & X-Continuous (2) Y- continuous & X-Discreate, (3)Y-Discreate & X-continuous (4) Y-Discreate & X-Discreate.

Data transformation is done for single data and that must be continuous. It can be x's or y's. Please go through the video and example in it.

So if i get a P value still less than 0.05 but my Confidence interval includes the 1 lamba value, that means i dont have to transform my data and just proceed as if its normal?

@@learnandapply But after watching your johnson video, it says if box-cox is not adequate( in my case it didnt transform) we should use johnson. Im abit lost haha. Should itransform my data if Box cox gives me a range of (-0,85 to 1.99) ?

@@learnandapply Im not sure if im right, but based on your video rules at the end, a lambda value of 1 inside ur interval means that "no transformation is necessary" . im not sure if this means we just stick with the original data or the boxcox is not applicable. When woudl the boxcox not be applicable anyways? How may i just continue with my data is my p value is significantly less than 0.05? , the johnson gives me a P value of 0.053 which makes us accept the null hypothesis.

Your data is already normal, if it contains 1 in the confidence interval. Can you please answer these 2 questions? 1. Why do you want to transform data? 2. Is your data contains negative values?
