Different Types of Variables and Groups

• What are the different types of variables in an experiment?

  1. Independent Variables: The factor being changed

  2. Dependent Variables: The factor being measured

  3. Control Variables: Factors kept constant throughout the experiment
• What is an independent variable?

  The factor you’re changing (manipulated)
• What is a dependent variable?

  The factor you’re measuring (responding)
• What are control variables?

  Factors that are kept constant throughout the experiment
• What are the experimental and control groups in an experiment?

  1. Experimental Group: Receives the manipulated independent variable

  2. Control Group: Serves as a baseline for comparison
• What is an experimental group?

  The group that receives the manipulated independent variable
• What is a control group?

  The group that serves as a baseline for comparison
• What is an example of variables in a plant growth experiment?

  • Dependent variable: Growth height
  • Independent variable: Watering plants
  • Controlled variables: Soil, sunlight, pot
• Control group: Group used as a reference point to compare with experimental groups.
