Hello!
I hope I can provide a clear explanation of what I am trying to do.
I am working on my IB Math Studies' IA. I have decided on the topic: Is there a relationship between a
student’s grade level and GPA?
I conducted a survey and recorded my results in a table.
I have made scatter plots for each grade level. I also solved Pearson's Correlation Coefficient just for freshman grade level (0.0118).
My question is, how am I going to find the correlation among ALL grade levels? Do I need to use Pearson's for all grades? If yes, how do I compare the values to determine the correlation?
I think I may be going about this the wrong way.
ANY help is very much appreciated!
