Hi, I've done a plaque reduction assay to analyze my possible plant activity, I used a HSV 2 virus at 6,5x10^3 as control, and I count (added file) the PFU... do I need to calculate something or I can make a graph with PFU results?
That's not a great graph, because it uses a thick bar to show means and a detonator to show standard errors. It does not give any actual information about how much data you had or how they were distributed. The two strange values for group D are not evident. And the asterisk is a bit of a mystery.
What is your hypothesis? Then maybe someone can help with a recommendation for testing. Since your groups differ by dosage, it would make more sense to see if the observed values are a function of dose, rather than treating each group as a distinct treatment. This gives you a directional hypothesis, and a lot more statistial power.
