Independent Variable

The factor that is changed by the scientist in an experiment.

Dependent Variable

The factor that is measured or observed in response to changes in the independent variable.

Control Group

A group in an experiment that does not receive the treatment or manipulation.

Experimental Group

A group in an experiment that receives the treatment or manipulation being tested.

Importance/Steps

The outline of an experiment
- Hypothesis
  - Prediction before the experiment
- Independent variable vs Dependent Variable
  - The independent variable is what the scientist changes (x-axis)
  - The dependent variable is what responds to the independent variable (y-axis)
- Control vs Experimental
  - Control group is the one that does not receive the treatment (used as a comparison)
  - Experimental group receives the treatment
How to improve experiments
- Increase sample size
- Strategy of measuring/keeping track
- Control and Experimental group present
- Peer review
- Repeat experiment
Basic Measurement
- Ruler measurement
