Statistical significance... difference
« on: May 11, 2010, 05:58:07 PM »
After some experiments using different substrates I got these yields:

         WG   H   DG   LP   FR

           0.406   0.251   0.520   0.527   0.502

Now that I come to discuss and write down everything properly I'm unsure if I can say that there is not a significant difference among what I got with DG,LP or even FR as susbtrates. I found some articles about statistical significance but still I don't know. Is there a correct way in statistics to say this? What is significantly different? Is it when a statistical significance is above 0.05? and how do I get this number? (Everything was meassured from triplicate assays by the way, the numbers I give here are the avarage values from the triplicates)
