I currently am conducting a study where I have three variables: one that is binary, and two numerical variables as measured on a ratio scale. Each of the subjects in my study has values for each of the three variables. Variables: Condition (binary): Values 0 and 1 Pre (ratio) Post...

Hi all, I apologise in advance if this is a very easy question - I may be struggling with the wording, or I might just be a bit slow. The obtained p value for a correlation analysis is .036 where n = 50. If an analysis had been undertaken with n = 90, and the same sample correlation value was...

Hi, I am in a design of experiments class at my university. We are analyzing rock-paper-scissor strategies and results among females and males on our campus. We gathered our data by grabbing 1 group at a time of 2 random males and 2 random females walking around campus and had each of them play...

I am trying to work out the most appropriate way to analyse some data from an experiment and would be really grateful for any ideas. The experiment involved getting people to perform an action using four different types of object, each obstacle type at two different sizes (same two sizes for...

I have 4 individual biological samples. For each sample we identified the SNP (single nucleotide polymorphism). Based on shared SNPs I need to prove that sample 1 is the same individual as sample 2, and different from sample 3 and 4. And sample 3 is the same as sample 4, and different from 1 and...
