Making Sense of Graphing The Advance Version

What do we measure? Variable: type of category you are tying to measure. Independent Variable: a variable that stands alone and isn’t changed by the other variables you are trying to measure. (cause) Dependent Variable: something that depends on other factors. (outcome/effect)

Graphing Variables Independent Variable: X-axis Dependent Variable: Y-axis

Test Scores Mr. Godinez is investigating students performance on their exams. He wants to find out if students test scores are related to the hours spend studying. Independent Variable Time Spent Studying Dependent Variable Test Score
