Explanatory Or Response Variables Questions and Answers

  • 1. 

    In questions that involved weight and height, height is likely to be the:

    • A.

      Response Variable

    • B.

      Explantory Variable

    Correct Answer
    B. Explantory Variable
    Explanation
    In questions involving weight and height, height is considered to be the explanatory variable because it is used to predict or explain weight changes, making weight the response variable. This is because height generally influences weight, with taller individuals typically weighing more due to their larger body mass.

    Rate this question:

  • 2. 

    On a scatter plot, which variable is shown on the x axis?

    • A.

      Response Variable

    • B.

      Explanatory Variable

    Correct Answer
    B. Explanatory Variable
    Explanation
    In a scatter plot, the x-axis represents the variable that is being used to explain or predict the values of the other variable, which is represented on the y-axis. Therefore, the variable shown on the x-axis is the explanatory variable.

    Rate this question:

  • 3. 

    On a scatter plot, which variable is shown on the y axis?

    • A.

      Response Variable

    • B.

      Explanatory Variable

    Correct Answer
    A. Response Variable
    Explanation
    In a scatter plot, the y-axis represents the response variable. The response variable is the variable that is being measured or observed and is typically the variable that is affected or influenced by the explanatory variable. The explanatory variable, on the other hand, is usually plotted on the x-axis and is the variable that is believed to have an impact on the response variable. Therefore, the correct answer is that the response variable is shown on the y-axis in a scatter plot.

    I measure the height and weight of 30 students to see if there is a relationship between height and weight. Height in this example is the:

    • A.

      Response Variable

    • B.

      Explanatory Variable

    Correct Answer
    B. Explanatory Variable
    Explanation
    In this example, the height of the students is being measured in order to determine if there is a relationship between height and weight. Therefore, the height is being used as the explanatory variable, as it is the variable that is believed to have an effect on the weight of the students. The response variable, on the other hand, would be the weight of the students, as it is the variable that is being measured and expected to change in response to the height variable.

      Response Variable

    • B.

      Explanatory Variable

    Correct Answer
    A. Response Variable
    Explanation
    In this example, weight is the response variable because it is the variable that is being measured or observed. The height of the students is the explanatory variable, as it is the variable that is being used to explain or predict the weight of the students.

    Rate this question:

  • 6. 

    I weigh 37 students and then time them over 100 meters to see if there is a relationship between weight, and how quickly they run 100 metres. In this example, time over 100 meters is the:

    • A.

      Response Variable

    • B.

      Explanatory Variable

    Correct Answer
    A. Response Variable
    Explanation
    In this example, the response variable is the time over 100 meters. This is because the time taken by the students to run 100 meters is the outcome or response that we are interested in studying or analyzing. We are trying to determine if there is a relationship between the students' weight and how quickly they run, and the time over 100 meters serves as the response or dependent variable in this analysis.

    • A.

      Response Variable

    • B.

      Explantory Variable

    Correct Answer
    B. Explantory Variable
    Explanation
    In this example, the amount of light each plant received is the explanatory variable. The explanatory variable is the variable that is manipulated or controlled in an experiment in order to determine its effect on the response variable. In this case, the amount of light is being manipulated to see if it has any effect on the growth of the seedlings, which is the response variable.
