Yes, this is possible and I have heard it termed as joint regression or multivariate regression. In essence you would have 2 (or more) dependent variables, and examine the relationships between independent variables and the dependent variables, plus the relationship between the 2 dependent variables.
Can we include more than one independent or dependent variable in a study?
Multiple Variables : It is possible to have experiments in which you have multiple variables. There may be more than one dependent variable and/or independent variable. This is especially true if you are conducting an experiment with multiple stages or sets of procedures.
Can you have more than one independent and dependent variable?
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. ... There may be more than one dependent variable and/or independent variable.
How many independents variables can you have in an experiment?
To insure a fair test, a good experiment has only ONE independent variable . As the scientist changes the independent variable, he or she records the data that they collect. The dependent variable is the item that responds to the change of the independent variable.
How many dependent variables can you have?
A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.
What is the difference between a dependent and an independent variable?
In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables. A Dependent variable is what happens as a result of the independent variable.
Is it possible to have no dependent variable?
In a scientific experiment, you cannot have a dependent variable without an independent variable . Example: You are interested in how stress affects heart rate in humans. ... It is possible to have experiments in which you have multiple variables. There may be more than one dependent variable and/or independent variable.
How many independent variables should I have?
You should generally have one independent variable in an experiment. This is because it is the variable you are changing in order to observe the effects it has on the other variables.
Can you have 3 independent variables?
In practice, it is unusual for there to be more than three independent variables with more than two or three levels each. This is for at least two reasons: For one, the number of conditions can quickly become unmanageable.
Can time be a dependent variable?
Time is always the independent variable . The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable).
Why is it okay to have more than one dependent variable?
Researchers in psychology often include multiple dependent variables in their studies. The primary reason is that this easily allows them to answer more research questions with minimal additional effort.
Is stress a dependent or independent variable?
Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
Which is dependent variable?
Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors . ... (Independent variable) causes a change in (Dependent Variable) and it isn’t possible that (Dependent Variable) could cause a change in (Independent Variable).
How do you know if a variable is independent?
You can tell if two random variables are independent by looking at their individual probabilities . If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.
What is the dependent variable in psychology?
The dependent variable is the variable that is being measured or tested in an experiment .1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
