In order to test whether his idea is accurate, he must first construct a falsifiable that defines a clear relationship between two variables. Raymond’s next step is to 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 variables that could confuse test results

Step-by-step explanation:

Answer 2

The above mentioned scenario is true.

Step-by-step explanation:

Sometimes , it might happen that some other variable other than the independent variable might be causing changes in the dependent variable. When conducting scientific researches, it is important that we have a proper knowledge that only the independent variable is causing the change in the dependent variable. All other factors should be kept constant and should be properly tested so that they are not other factors which might be causing the change in the dependent variable.
