The independent variables in the Brown-Peterson experiment are the time interval (short vs. long delay between presentation of information and recall task) and the type of interference (interference task vs. no interference task).
The two types of variables in an experiment are independent variables, which are controlled by the experimenter and can be manipulated, and dependent variables, which are the outcome or response that is measured in the experiment and may change in response to the independent variable.
I think it has to do with the quasi you cannot randomly assign people to groups and cannot infer causality. With correlational you are simply examine the relationship between two nominal variables.
Controlling variables in an experiment is important because it allows researchers to isolate the effects of the independent variable on the dependent variable. This helps to ensure that any observed changes are actually due to the manipulation of the independent variable, rather than other factors. Controlling variables also helps to increase the reliability and validity of the study results.
The independent variable is the amount or type of exercise that the participants engage in. The dependent variable is the participants' weight measurements.
The independent variable is the one in which you can control. So say you are measuring the speed of a car. You set up a length of 50 M and you take the stopwatch to time how long it takes for the car to reach 50 M. You can't control the time, but you have controlled how far the car goes. Therefore, the distance is the independent variable in this problem.
Variables that do not change in an experiment are independent variables.
Variables that do not change in an experiment are independent variables.

the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.

the independent variable controls the dependent variables
It is easier to control independent variables
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
Independent variables are those that you change in an experiment. Dependent variables are the ones that you measure in an experiment. Dependent variables are influenced by the independent variables that you change, so they are dependent upon the independent variable. Generally, experiments should have only one independent variable.
the dependant variable
There are 2 variables and they are independent and dependant.
In a controlled experiment, the Independent variable refers to the variable that is manipulated or altered. The dependent variable, meanwhile, is the result of the experiment.
