Determining cause and effect is one of the most important parts of scientific research. You want to find out how blood sugar levels are affected by drinking diet soda and regular soda, so you conduct an experiment.
The value of a dependent variable depends on an independent variable, so a variable cannot be both independent and dependent at the same time. It must be either the cause or the effect, not both! Yes, but including more than one of either type requires multiple research questions. For example, if you are interested in the effect of a diet on health, you can use multiple measures of health: blood sugar, blood pressure, weight, pulse, and many more. Each of these is its own dependent variable with its own research question.
You could also choose to look at the effect of exercise levels as well as diet, or even the additional effect of the two combined.
Each of these is a separate independent variable. To ensure the internal validity of an experiment , you should only change one independent variable at a time. Have a language expert improve your writing.

Independent and dependent variables Published on May 20, by Lauren Thomas. Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors.
For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does. Many people have trouble remembering which is the independent variable and which is the dependent variable.
An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense.
