Independent Variables Independent variables in a hypothesis are those that influence or cause changes in another variable. In other words, an independent variable is something that is chosen by the researcher to cause a change in another variable . Dependent Variables The dependent variables are those variables are believed to be influenced by the independent variable (Schaefer & Lamm, 1992:38). Example: Independent and Dependent Variables Higher levels of education produce greater earnings. Education is the independent variable (it causes the change in income levels). Income level is the dependent variable. The income an individual earns "depends" or is determined by the influence of education.

Unformatted text preview: Correlation One of the most common research mistakes is to assume that a high correlation between two variables means that one variable (independent) causes some change in another variable (dependent). A correlation exists when a change in one variable coincides with a change in another variable . The fact that a correlation exists means that the two variables are associated statistically with one another. However, the mere fact that associations exist, does not necessarily mean that a change in one variable causes a change in another variable. Correlations are an indication that causality may be present. They do not necessarily indicate causation (Schaefer & Lamm, 1992: 38)....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
