Q. Melissa is taking a standardized test. The more questions she answers correctly, the greater her final test score will be.\newlineqq = the number of questions Melissa answers correctly\newliness = Melissa's final test score\newlineWhich of the variables is independent and which is dependent?\newlineChoices:\newline(A)ss is the independent variable and qq is the dependent variable\newline(B)qq is the independent variable and ss is the dependent variable
  1. Define Relationship: Determine the relationship between the number of questions Melissa answers correctly qq and her final test score ss. Since the final test score is a result of how many questions are answered correctly, the number of questions answered correctly is the cause and the test score is the effect.
  2. Identify Independent Variable: Identify the independent variable. The independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. In this case, the number of questions Melissa answers correctly qq is the independent variable because it is what she can control and change.
  3. Identify Dependent Variable: Identify the dependent variable. The dependent variable is the variable being tested and measured in a scientific experiment. Melissa's final test score ss is the dependent variable because it depends on the number of questions she answers correctly.
  4. Choose Correct Answer: Choose the correct answer choice based on the identification of independent and dependent variables. Since qq is the independent variable and ss is the dependent variable, the correct choice is (B) qq is the independent variable and ss is the dependent variable.
