Experiments 2A - Analysis of experiments in two factors by hand

[@experiencetheworld3178]

well structured slides, having good knowledge and really best teaching skills...........Thanks for uploading these

[@zhongminling8712]

very clear and easy understand.

Sir, I have some confusion about the OFAT vs two-factor design. if I will use temperature and time(two factors) as independent variables and heating value as a response: in this case how we can explain the experimental advantages of DOE over OFAT. It is requested to kindly give me a reply.

Nice and simple understanding 🙏🙏

[@muhammadaziziazizi6223]

what is analyse method that you used ?

[@georgygursky4303]

Good explanation, Thanks!

Is there an easy way to generate interaction plots for all combination of factors in R?

[@kpoplove9819]

Hello, do you have a video having 2 factors with 3 levels. High, medium , low level

[@KevinDunn13]

Yes, in part 5 of the course we handle multiple levels. You can use -1, 0 and +1 as coded values for 3 categorical levels of low, medium and high, if the even spacing makes sense for such a variable.

Thank you sir

[@kpoplove9819]

can you give me example of mathematical model having 3 levels ?

i have stuck to analyse two factors analysis and how to read output in SPSS. could you help me?

[@abderhmanmanchawi5277]

Thank you very much

I wanted to add a third factor in the time level, maybe 240 seconds. let's just say I'm running my experiment at constant temperature which would not burn popcorn i left it on for this long. so 160, 200, and 240 seconds. still only considering white corn and yellow corn. how can i represent the factors in regards to +/- terminology? I got stuck designing this experiment.would this be a 2^5 experiment?

[@KevinDunn13]

Ismael Hernandez : in a later video, in part 3 and part 5 we show how you can expand the range of values of a factor in the +/- terminology. We call that coded variables. It is fairly simple. It is not a 2^5 experiment though. That is something else, and we cover that in module 3 and 4.

How do you get the outcome values?

[@KevinDunn13]

Each outcome value is the measured result from running an experiment.

[@abdulqadirmuhammadabdullah3470]

It is on the software?

Thanks

this was great
