There is the mathematical use and statistical use of the word "dependent" as explained on the related link. The mathematical use is a dependent variable is the outcome of a function with one or more independent variables. The statistical definition in the setting of an experiment, is similar, it is a variable which is expected to be affected by changes in independent variables. Example: If I don't eat (quantity of food- independent variable), I will be hungry (dependent variable). I will not have as much energy (second dependent variable). But nothing is perfect in experimentation. The circumstances of the experiment with numerous unknown relationships may cause unexpected results. In observational studes, with typically less control, variables can be hypothesized (or conjectured) to be related, i.e. global warming causes artic ice to melt, and artic ice melting leads to more global warming. This would also be called a feedback effect. I can produce a dependent series of numbers from an independent series. If I take a series of random numbers of size N which come from a given distribution, and rank them from low to high , with n = 1 for the lowest and n = N for the highest, the ranks become dependent variables. A change in one value could affect the rank of another variable. I have included some more information on dependent variables. See related links.

Does a bi variate study have two dependent variables?
It does not have to. It is simply a study where two variables have a joint probability density function. There is no requirement for both variables to be dependent - one may be dependent on the other (which is independent).
What statistical test to run when comparing the effects of two dichotomous variables on a dependent variable Anova Manova Why would you choose it?
If there are only two variables, then the dependent variable has only one variable it can depend on so there is absolutely no point in calculating multiple regression. There are no other variables!
What is the differecnce between independent variables and dependent variables?
Every time the independent variables change, the dependent variables change.Dependent variables cannot change if the independent variables didn't change.
What are independent and dependent variables in science?
Dependent variable is the variable that can be measured. However, the independent variable is the variable that changes in the two groups.
13 What is the relation between dependent and independent variables?
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.

What are the two important variables in a research title?
Dependent and Independent variables
What are the two types of variables in an experiment?
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.
Can you have two dependent variables?
It is generally not recommended to have two dependent variables in a single analysis, as it can complicate the interpretation of results. It is usually clearer to analyze each dependent variable separately in order to understand the relationship with the independent variable. If the dependent variables are closely related, consider creating a composite score or index to represent the construct.
Independent and dependent are types of what?
Independent and dependent are types of variables. These variables are used mostly in science and math. When using independent variables you can control them dependent variables you cannot.
What are indepenent and dependent variables?
Dependent variable change and independent variables do not change.
How do the independent and dependent variables in an experiment compare?
the independent variable controls the dependent variables

What are the dependent variables in an experiment?
Dependent variables are the outcomes or responses that are measured to assess the effect of manipulating the independent variables. They depend on the changes made to the independent variables in the experiment.
