Just wanted to ask everyone on here if I got the right idea. I'm doing research on algal cultures and I have data from 6 treatments which have three replicates each. A friend of mine did similar research before and he did a one way anova test on his data.
Just wanted to clarify if my thought process is correct. The treatments are the independent variables, and the anova is primarily done to see whether there is a significant difference in the means between treatments?
And regarding SPSS, does the program provide the superscripts for the Tukey's HSD? Or do you have to so it yourself?
