construct a falsifiable (Theory, Law or Hypothesis)
that defines a clear relationship between two variables. Raymond's next step is to (Design an experiment, Complete mathematical calculations or Propose an explanation.)
that would isolate and test the relationship between the two variables. This task can be pretty
daunting because Raymond will need to identify and eliminate any (Confounding, Dependent or Independent) variables that could confuse test results.
