when raymond observes certain natural phenomena, he often forms ideas about their causes and effects. suppose that raymond surmises that
leaves change color in autumn due to scarcity of sunlight. 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
would isolate and test the relationship between the two variables. this task can be pretty daunting because raymond will need to identify and
that
eliminate any
variables that could confuse test results.
