Independent Variable , Dependent Variable, Theory, and Hypothesis

Research on alcohol has shown that the more a person drinks, the worse their motor skills will become, such as walking, coordination, and balance. Dr. Smith decided to test this claim by randomly assigning volunteers to two groups in which people either drank alcohol or not. Ten people drank 6 oz. of vodka in one hour; 10 people drank 6 oz. of water in one hour. Dr. Smith predicted that people in the alcohol group will not be able to balance on one foot for as many seconds as people in the water group.

What is the Independent Variable (IV)?

What is the Dependent Variable (DV)?

Please identify the theory!

Please identify the hypothesis!

Thank you very much for your help!

IV = The fact there is an alcohol and non alcohol group; it's the thing you change.

DV = Their motor skills and whether it gets worse or not; it's thing you measure

The hypothesis is this: 'Dr. Smith predicted that people in the alcohol group will not be able to balance on one foot for as many seconds as people in the water group.'

The theory being: 'Research on alcohol has shown that the more a person drinks, the worse their motor skills will become, such as walking, coordination, and balance.'

Hope this helps

Thank you very much Deyesy, you are a lifesaver.
