which is a better example of dependant/independant variable?
this is my hw for psychology 101. I am having trouble deciding which to use. The example must include dependent/independent variables and give positive and negative correlation. which is the best choice?
Crying and being held-among babies, those who are held more tend to cry less (or phrased as babies who are held less tend to cry more)
1.Dependant-crying
2.Independent- baby being held
A car manufacturer wants to know how bright brake lights should be in order to minimize the time required for the driver of a following car to realize that the car in front is stopping and to hit the brakes.
1.What is the independent variable? (brightness of brake light)
2.What is the dependent variable? (time to hit brake)
As the temperature increases the amount of clothing people wear will decrease, when the temperature decreases the clothing increases.
1.Dependant- amount of clothing being worn
2.Independent- temperature
Crying and being held-among babies, those who are held more tend to cry less (or phrased as babies who are held less tend to cry more)
1.Dependant V – crying
2.Independent- baby being held
3. Negative correlation
A car manufacturer wants to know how bright brake lights should be in order to minimize the time required for the driver of a following car to realize that the car in front is stopping and to hit the brakes.
1.What is the independent variable? brightness of brake light
2.What is the dependent variable? time to hit brake
3. Positive correlation – increased brightness should result in increased response
As the temperature increases the amount of clothing people wear will decrease, when the temperature decreases the clothing increases.
1.Dependant- amount of clothing being worn
2.Independent- temperature
3. Negative correlation
They are all plausible choices. If I was to choose, I would likely choose A.
