Independent + Dependent Variables

The information you collect in an experiment in order to answer a question is called

• Charts

• Graphs

• Data

• Hypotheses

This type of variable is what you DON'T change in a lab

• Control

• Independent

• Dependent

A graph can be described as all of the following EXCEPT:

• A tool to be interpreted only by trained scientists and mathematicians

• A good way to describe the relationship between to variables

• A mathematical design

• A model

A variable that is unchanged throughout the experiment is the:

• Controlled Variable

• Experimental Variable

• Independent Variable

• Dependent Variable

The independent Variable in a lab can be described as the variable:

• Represented on the X Axis

• Causing the change in the dependent Variable

• Over which a scientists usually has direct control when designing an experiement

• All of the above

The independent Variable is found on the:

• X Axis

• Y Axis

The dependent Variable is found on the:

• X Axis

• Y Axis

The independent Variable is:

• What you keep the same in the experiment

• What you change in an experiment

• What you measure in an experiment
