What is a confounding variable


          A confounding variable is a variable that correlates with both dependent and independent variable.
Example: For example if there is a group of are scientists studying smoking and deaths in America they would see how many people have died from consuming too much cigarettes and they would see the statistical relationships between people smoking and deaths in the united states. They would see if people who smoke in United States increase the rate of deaths in a year for the United States.
