Difference between Observational Studies and Clinical Trials In clinical trails, the researcher would divide the participants into two more groups and control the way they behave, while noting the changes or results. Observational studies and clinical trials are two different methods that researchers use to collect data and test theories. When conducting research, it is important for a researcher to be able to gather data by examining various subjects and being able to job down the outcome. Observational studies and clinical trials are different from each other in terms of interference of the researcher. In Observational studies, the researcher does not interfere, while in clinical trails the researcher creates two groups with controlled experimentation.

- The objective of clinical trials is to test new therapies to determine if they have an acceptable level of safety and demonstrate a clinical benefit in helping patients with the disease they targets. If a new treatment is proven to work, then patients in the study would be the first to benefit from it. That said, there is no guarantee that any clinical study will be successful. Requirements for clinical trials are strictly managed by the Food and Drug Administration.

Correlational Methods vs. Experimental Methods Correlational methodologies and experimental ones are the two approaches to doing research. Experimental studies allow the researcher to control the variables in the study, while correlational ones involve just looking at the data that already exists. Experimental studies allow the researcher to draw conclusions about one variable causing changes in another.
