Custom DOE do 3 replicates of each combination

Agustin

I'm trying out the custom DOE tool and I'm not sure what the replicate runs option does.

I would like to specify that I want 20 combinations for example but I was to run each of those combinations 3 times, so we have 3 replicates of each combination and 60 runs in total.

What would be the best way to do this? 

 

Thanks

Replicates runs just makes one of your run conditions repeated. 

 

It sounds like you plan to repeat your 20 runs 3 times?

In this case just add a column for each repeat. From here you have some decisions to make about repeated measures.

 

For example: I have 20 conditions I want to try and I'm running the experiment in a 96 well microtiter plate, so its easy to have repeats of the 20 conditions, plus I know there might be random position effects, so repeats are a good idea.

Are all 60 well independent runs? Well, no. They are all dependent on the one run. After I have all the data I would likely take the mean of the three repeats and use that as the response in my analysis of the experiment.
