Fractional Factorial Design (DoE) Simply explained

What is a Fractional Factorial Design? A fractional factorial design is a type of experimental design used to analyse the effects of several factors (or variables) on a response variable. What is the difference with a full factorial design? In a full factorial design, every possible combination of factor levels is examined. Conversely, a fractional factorial design strategically excludes certain combinations. This reduce the number of experiments while still capturing essential information about the system's behavior.

What should I say? Thank you guys, cheer for you, or maybe pay tribute to your extraordinary efforts to share knowledge.
I'll share & tell everyone I know about the DATAtab TH-cam channel with my colleague at the hospital, the research team, and students.
I hope and sincerely wish you to keep up this work for us who can't get access to up-to-date biostatistics and are having a hard time completing their postgraduate studies in my country.
Blees you & your beloved ones.
❤❤❤❤❤❤❤❤❤

Hi, many many thanks for you nice feedback and for sharing DATAtab! We appreciate that! Regards Hannah & Mathias

Your videos are amazing! It is SO easy to understand all the topics you explain in your videos thanks to clear language, bold text when necessary, examples, visual models and figures... all of this in a step by step approach. If every professor and educational video did it like you do, the world would be a better place! Thank you for making knowledge accessible and understandable. You got yourself a new subscriber!
Question: Could you maybe make a video on time series forecasting, and the ARIMA model? :D

Please how do you calculate to get the RESPONSES?

[@datatab]

Hi, thanks for you comment! You don't calculate the responses, the responses are the results of the experiments and I just used random values as example data!

[@syedmdabid7191]

All the fractions whether it's+ve Or --ve have the factorial value. But:
All the negative natural number don't have the defined factorial value.

[@syedmdabid7191]

And So all the positive and negative IRRATIONAL NUMBERS have defined and real factorial Value..

hmm
