I'm having a problem with a factorial design in Minitab, as it is not as clear how to proceed as all problems I've had thus far.
The problem is to create a factorial design with two factors where the first factor, Environment, which has two levels - H2O and Salt H2O whose values overlap (i.e. they cannot be differentiated by simply stating a value for low which is only met for H2O and one value for high which is only met by Salt H2O).
The second factor is Frequency and it is 10 for four measurements and 1 for four others.
The data is structured as a table such as:
Environment H2O Salt H2O 10 value value Frequency
The problem is that I don't know how to create this in Minitab. I'm aware that it will be a 2$\times$2 factorial design with 4 replicates, but as mentioned earlier I don't know how to define the Environment factor. I also don't understand how to put in the response variable.
I guess it will be the values in the table, but to what do these entries in the table correspond to in Minitab?
