What is an independent variable (IV)?
Something you change in an experiment
What role does the independent variable play in an experiment?
It is the cause in a cause-and-effect relationship
How does the independent variable relate to the dependent variable in an experiment?
The independent variable is changed to observe effects on the dependent variable
What does the dependent variable measure in the sleep and memory experiment?
Changes based on the amount of sleep
How does a dependent variable relate to an independent variable?
The DV changes based on the IV
What is the dependent variable in the sleep and memory experiment?
Memory performance
What is a dependent variable (DV)?
Something you measure in an experiment
How is the Dependent Variable (DV) controlled in an experiment?
It is not controlled directly
What does the Dependent Variable (DV) represent in an experiment?
What you measure
What does DV stand for in experiments?
Dependent variable
How is the Independent Variable (IV) typically measured?
Usually has different levels
What does IV stand for in experiments?
Independent variable
In an experiment, what does the dependent variable represent?
The effect in a cause-and-effect relationship
How is the Dependent Variable (DV) typically measured?
Measured for changes
What role does the Independent Variable (IV) play in an experiment?
It acts as the cause
What is the relationship between Independent Variable (IV) and Dependent Variable (DV)?
IV is manipulated to observe effects
DV is measured to assess changes
Understanding their relationship reveals cause-and-effect
What is the role of the independent variable (IV) in an experiment?
It is manipulated to see effects on DV
What are the key differentiations between IV and DV?
IV is manipulated by the researcher.
DV is measured to observe changes.
IV is the cause, DV is the effect.
What is an independent variable (IV)?
It causes the dependent variable to change
What is a dependent variable (DV)?
It is measured to observe the effect
How does the independent variable affect the dependent variable?
The IV is manipulated to observe changes in the DV
What is the role of the dependent variable (DV) in an experiment?
It is observed to see effects from IV
In a study on sleep and memory, what is the IV?
The amount of sleep
What does more sleep cause in terms of memory performance?
Better memory performance
In a study on sleep and memory, what is the DV?
The memory performance
What role does the Dependent Variable (DV) play in an experiment?
It acts as the effect
How is the Independent Variable (IV) controlled in an experiment?
It is manipulated by the researcher
In an experiment testing sleep's effect on memory, what is the independent variable?
The amount of sleep
What is the cause-and-effect relationship in research?
The IV causes changes in the DV
The IV is manipulated by the researcher
The DV is measured to observe effects
How does the independent variable (IV) relate to the dependent variable (DV)?
IV is the cause, DV is the effect
