<p>I keep on seeing response variable and explanatory variable popping up on FRQ's and MC questions. Can someone explain what they are and what are the differences? Thanks! A example might help too. =]</p>
<p>Response variable is the effect/outcome. It’s what changes (also known as dependent variable).</p>
<p>Explanatory variable explains the variation in the response variable. In experiments, this is the independent variable (what you change).</p>
<p>In simple terms, explanatory is the x variable and response is the y in an LSRL.</p>
