Independent Variable, Dependent Variable

200

What is an independent variable?

a variable whose variation does not depend on that of another

300

What is a dependent variable?

400

Dependent variable meaning/purpose

responds to change, collect data from this, cause and effect we create, "What am I measuring or looking for?"

200

Definition of Testable Questions

Specific inquiries designed to be answered through scientific investigation, directly comparing variables to produce measurable, objective data

300

Definition of Dependent Variable

​the outcome or response being measured in an experiment or study, whose value "depends" on changes made to the independent variable​

400

Definition of Indapendant Variable

the factor that is changed or controlled in a scientific experiment to test its effects on a dependent variable

500

Definition of Scientific Notation
