Which variable can you change independent or dependent?
The independent variable is what you change, and the dependent variable is what changes as a result of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
Can you have a dependent variable without an independent variable?
The dependent variable responds to the independent 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.
What is usually the independent variable?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. 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.
Which is the cause of an independent variable?
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
When do you call a variable a dependent variable?
Variable are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
Which is the dependent variable in an experiment?
The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
Can I include more than one independent or dependent variable?
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.
