VariablesVariables

• The independent variable is the variable that you change

• The dependent variable is the one that is observed and measured

• The controlled variables are any other factors in the experiment that might affect the outcome that are kept the same

• The independent variable is changed first, then the dependent variable changes and we measure it

Experimental DesignExperimental Design• Control group: the group in which all

variables are kept the same, used for comparison

• Experimental group: (test group) all conditions are kept the same except for the one being tested

A student hypothesizes that the pulse rate of a person and background music that is playing are related. The student designs an experiment to test this hypothesis. What would be an appropriate control for this experiment?

EXAMPLE – making up your ownProblem: How does sunlight affect plant growth?

Hypothesis: Plants that are given more sunlight will grow faster.

Independent variable: (what are we changing?)

sunlightDependent variable: (what will we observe?)

plant growthControlled variables: (what else could affect the

experiment that we should keep the same)

water, soil type, plant species, age of plant, container size, temperature, etc.
