    Study Notes

    Independent Variables in Research

    • An independent variable is a factor that is manipulated or controlled in a study to observe its effect on a dependent variable.
    • In statistics, independent variables are also referred to as predictor variables or explanatory variables.

    Types of Independent Variables

    • There are two main types of independent variables:
      • Manipulated Variables: Directly controlled in experiments to observe effects.
      • Measured Variables: Observed and recorded without manipulation, often in correlational studies.

    Examples of Independent Variables

    • An example of an independent variable could include the dosage of a medication in a clinical trial or the amount of study time in an educational research study.

    Purpose of Independent Variables

    • The purpose of estimating the relationship between independent and dependent variables is to determine if and how changes in the independent variable can explain or predict changes in the dependent variable, enhancing the understanding of the nature of their relationship.
