Detailed explanation-1: -The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.
Detailed explanation-2: -Dependent variables are the measured behaviors of participants. They are dependent because they “depend on” what the participants do. The most obvious example is text entry speed, measured, for example, in words per minute.
Detailed explanation-3: -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.
Detailed explanation-4: -A measurement variable is an unknown attribute that measures a particular entity and can take one or more values. It is commonly used for scientific research purposes. Unlike in mathematics, measurement variables can not only take quantitative values but can also take qualitative values in statistics.
