Minitab Statistical Software: Design of Experiment

Design of Experiment (DOE) is a powerful technique for process optimization that has been widely used in all types of industries. In DOE, we can separate important and unimportant factors, identify the relationships between factors and responses and then determine the optimal factor settings. In short, DOE helps us understand the process rapidly.

First, i would like to thank you for making this great presentation on Minitab, especially DOE. It's helped me a lot.

Thank you for this informative session. It would be more impactful if the medium of communication was clear. It may be because of Persons's physical limitation.

Thank you very much for your contributions, it is honestly amazing the stuff out there that is free to access, why do we pay for education?

Thank you very much for this presentation. This is very good.

hello. It was a wonderful presentation which has cleared many of my doubts. I have some query, it would be kind of you if you can help me.
1) I want to study the effect of various factors on enzyme production. Factors i want to study are around 10. So I should use plackett burman design or full factorial design.??
2) After which I want to know which factors effect the production and then optimize it. So which design is suitable.
3) After we select any design we save this document run our experiment and come back n add our values in next block and proceed for the analysis right?
4) lastly how can we get predicted values from the software and compare it my actual values. Where is this option available.
Thank you

Thank you for the helpfull video! But i would like to ask a few things..

1. Could we processing data twice first before we entering the optimization and verification stage? In my case, i have 19 runs of formulation that i got using simplex centroid design method. From that 19 samples, i want to get 4 best samples from 1 response result. After i get 4 best samples, i test the 4 samples again with different responses. And then the response results of 4 samples is used in optimization and verification stage. Is it possible to do that in one time (not in separated time when i processing data to get 4 best samples, and processing data to have optimization formula)?

2. Could you elaborate again to me about what is the difference between simplex centroid design and simplex lattice design in a easier way?🙏🏻

I'm sorry for my english.. i hope you would understand what i mean. Thank you in advance🙏

Hi Mam. This was a very nice and clear presentation. Can I use factorial design for 3 factors and 3 levels?

[joeljoel]

Very informative maam. Easy to understand.

[adibcs]

I have run the experiment and have my own factorial design.. can i just analyze the data using my own factorial design.. How should I do?

[fatmaelmaghraby]

thank you very much, but i want calculate adequate precision from minitab and lack of fit

[foodtechnologist]

I wish my teacher also explain like you😢

[arfasafaraz]

Sorry, how to download the software? Any link?

Appreciate you r video, but you seriously need to work on your English, its really difficult to understand what you are talking about, this issue especially gets more pronounced when you explain on subjects that there is no presentation tool available in the session
