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 “answer”
that defines a clear relationship between two variables. raymond's next step is to “answer”
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 “answer”
variables that could confuse test results.
