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.

A good experiment should have a limited number of variables, typically one or two, to ensure that the relationship between the variables can be clearly identified. Having too many variables can make it difficult to determine which factors are influencing the outcome of the experiment.

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?
The number of variables that can be tested at a time may vary depending on the experimental design and resources available. In practice, it is common to test one to three variables simultaneously in order to effectively analyze and interpret the results. However, some experimental designs may allow for testing more variables at once.
How many variables do you test within one experiment?
It is recommended to test one variable at a time in an experiment to ensure that any observed effects can be attributed to that specific variable. This approach allows for clearer interpretation of results and helps to avoid confounding factors that might impact the outcome.
What is true about a controlled experiment?
A controlled experiment involves manipulating one variable (independent variable) while keeping all other variables constant in order to observe the effect on another variable (dependent variable). This allows for causal relationships to be inferred between the independent and dependent variables. Control groups are used in controlled experiments to provide a baseline for comparison.
How many variables should have an experiment?
A experiment should only have one variable.
How many variables should you have to change in an experiment?

How many variables should each experiment have?
one
How many variables should you change at a time in an experiment?
8
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
How many variables should you have when you start an experiment?
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.

How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
