What type of research method would it be? Gloria wanted to know how many children under ten were using the computers in the library. So, she stationed herself at her local library for several days and counted each child. ¬†
A. Experiment B. Observational study C. Survey D. Research review E. Unpublished report
The correct answer to this question is B, Observational study. This type of study is used in many fields, like social science, statistics, and psychology. Observation study involves an inference taken from a sample population. Due to ethics, the researcher has no control over the independent variable.
One example of observational studies that all may be familiar with are the effects that treatments have on subjects. In the example provided in this question, the independent variables are the children. She had no control over who they were or how many visited the computers. Instead of controlling them, she is just observing them.
