What's the difference between a independent variable and dependent variable

The dependent variable depends on the independent variable.

Step-by-step explanation:

The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable... The values of the independent variable can be changed as per requirement, by the researcher... Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment. An independent variable is a presumed cause whereas dependent variable is a measured effect. In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x
