Our school project requires Statistical Analysis and I'm not quite knowledgable about it. I'm reading right now and I've learned some things but I'm still confused.
So what I did was I used different sponges with different doses to test their antimicrobial effect. So basically, pathogens were placed in wells and different extracts with different doses from different sponges were used.
I had sponges 1-7 with a high dose, medium dose and low dose.
I have 4 controls sterility control (no pathogen and extract),
growth control(with pathogen only), positive control (with antibiotic and pathogen) and negative control.
I assume there should be only one control which is growth control and sterility ,negative and positive should be considered as treatments.
So to summarize I had 7 sponges with different doses. I also had different treatments.
My question is should I use one-way anova here. If not, what should be the most appropriate?
Another is, should I remove sterility control here since it was simply a test for sterility?
