Which research type focuses on statistical relationships without manipulating variables?

• A. Correlational research
• B. Experimental research
• C. Qualitative research
• D. Pure basic research

Answer: (A)

Correlational research examines how variables are related to one another in the real world, without manipulating or assigning participants to different groups. It looks at natural variation and uses statistics to describe the strength and direction of the relationship, typically with a correlation coefficient. However, because nothing is controlled or randomized, you can’t infer causation from a correlation alone—two variables can be related due to a third factor or coincidence. This differs from experimental research, which involves manipulating an independent variable to observe effects on a dependent variable; qualitative research focuses on non-numeric data to understand meaning and context; and pure basic research aims to advance theory without immediate practical applications. Therefore, focusing on statistical relationships without manipulation points to correlational research.
