If changing one variable seems to lead to a change in another variable, this shows ________ but does not necessarily prove ________.

A) a paradigm shift; causation
B) correlation; causation
C) causation; correlation
D) applied research; a paradigm shift

When changing one variable seems to lead to a change in another variable, it demonstrates correlation. However, correlation alone does not prove causation as there may be other variables or factors that are influencing the relationship between the two variables. Therefore, option B is the correct answer, which states that the scenario demonstrates correlation but does not necessarily prove causation.
