There should be one dependent variables. Depending on the type of research you are doing, the amount of independent variables will change.
If you are doing research on a large scale, you will use more independent variables. If it's on a small scale, you will use very little. If you are not able to run your regression it means your sample size is too small or you have too many independent variables.

What should be close to the real thing in an experiment?
In an experiment, the conditions, variables, and procedures should closely resemble real-life situations to ensure the results are valid and applicable to the real world. This includes controlling for as many extraneous variables as possible and designing the experiment in a way that reflects the natural environment or scenario being studied.
How many experimental variables should you have?
It is recommended to only have one experimental variable in a scientific study to properly isolate its effects and draw valid conclusions. Multiple variables can complicate the results and make it difficult to determine which variable is responsible for the observed effects.
How many variables can be tested at a time?
An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.
How many variables do you test within one experiment?
Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.
What is true about a controlled experiment?
Scientists perform controlled experiments in order to reduce as many third variables as possible. This means they are trying to prevent variables not directly related to the study from influencing the results.
How many variables should have an experiment?
A experiment should only have one variable.
How many variables should each experiment have?
one

How can you eliminate confounding variables in your experiment?
To eliminate confounding variables, or variables that were not controlled and damaged the validity of the experiment by affecting the dependent and independent variable, the experimenter should plan ahead. They should run many checks before actually running an experiment.
How many variables should be studied in an ideal scientific experiment?
ONE :)
How many variables should be tested on the experimental group in an experiment?
Just one at a time
How many variables does a controlled experiment have?
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
How many variables should change in a scientific experiment?
It depends what kind of experiment you do. For some you just need one. For others you may change two variables. In most cases you only change one

one
