Due to the presence of confounding variables in research, we should never assume that a correlation between two variables implies causation. When an extraneous variable has not been properly controlled and interferes with the dependent variable (i.e., results), it is called a confounding variable. For example, if there is an association between an ...
Suppose we wanted to measure the effects of caloric intake (IV) on weight (DV). We would have to try to ensure that confounding variables did not affect the results. These variables could include the following: 1. Metabolic rate: If you have a faster metabolism, you tend to burn calories more quickly. 2. Age: Age can affect weight gain differently,...
