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!

Kindly check explanation

Explanation:

From the context described above :

Independent variable (IV) : This is the variable which is varied, they are the two different treatment given to the group of participants. Hence the independent variable (alcohol (vodka) and non-alcohol (water)).

The dependent variable (DV) : variation in response obtained due to changes in the independent variable applied. This is the change in motor skill of participants.

The theory is based on the fact drawn from the research that an individual's motor skills worsens with increased consumption of alcohol.

The hypothesis 'is aimed at establishing that participants in the non-alcohol group will maintain a better balance for a longer period on one foot than those in the alcohol group.

an aneroid barometer is different from a mercury barometer in that it provides readings that increase as air pressure increases.

hope it : )
