This is the term for a testable idea.
What is a hypothesis?
Scientific procedures designed with the purpose to test a hypothesis in a controlled setting
What is an experiment?
This is a testable idea.
What is a hypothesis?

What is the Independent Variable and Dependent Variable?
Independent Variable: amount of time spent studying
Dependent Variable: Increase grades

What is the independent variable?
Experiments in which neither the experimenters nor the participants know the objects' identities in the setup.
What is a double-blind experiment?
this is a scientific procedure that is completed outside and the scientist has no control of conditions
What is a field study?
In ____________ experiments, information about the test is kept from the participants to reduce bias.
What are blind experiments?
Independent Variable: Amount of time spent practicing
Dependent Variable: Increased chance of winning a basketball game
What is the Hypothesis
What is, "If I spend more time practicing, then my chances of winning basketball games will increase because practice makes perfect?"

What is dependent?
