How do you describe the relationship between independent and dependent variables?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
Which variable is influenced by the other?
The idea is that one variable is the effect of another variable or, to say it another way, that one variable precedes and/or causes another. The dependent variable is the variable to be explained (the ‘effect”). The independent variable is the variable expected to account for (the “cause” of) the dependent variable.
Which variable is the cause and effect?
independent variable
The cause is called the independent variable; and the effect is called the dependent variable.
Can a study have 2 dependent variables?
It is called dependent because it “depends” on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable. It is possible to have experiments in which you have multiple variables. There may be more than one dependent variable and/or independent variable.
Which is an independent variable of the DV?
For the following hypotheses name the IV and the DV and operationalise both variables. 1. Women are more attracted to men without earrings than men with earrings. 2. People learn more when they study in a quiet versus noisy place. 3. People who exercise regularly sleep better at night.
Who is Cara Lustik and what is a dependent variable?

Which is the dependent variable on a driving test?
Researchers are interested in looking at how alcohol use influences reaction times while driving. The amount of alcohol a participant ingests is the independent variable, while their performance on the driving test is the dependent variable.
How are independent variables related to dependent variables?
In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent variable. 2 Manipulating independent variables and measuring the effect on dependent variables allows researchers to draw conclusions about cause and effect relationships.
