A study is conducted to determine whether the implementation of a new scheduling pattern has a positive effect on the job satisfaction of staff nurses. Nurses are randomly assigned to the experimental group (new scheduling pattern) or comparison group ("usual" scheduling pattern). This is an example of which type of study?
1. Pre-experimental study
2. Quasi-experimental study
3. Comparative study
4. Experimental study

Rationale 1: Pre-experimental designs are those experimental designs that are weak and in which the researcher has little control over the research. This is not the case in this study.
Rationale 2: Quasi-experimental designs are those in which there is either no comparison group or subjects are not randomly assigned to a group. That is not the case in this study.
Rationale 3: The difference between an experimental study and a comparative study lies in the researcher's ability to manipulate the independent variable. In comparative studies, there is no manipulation of the independent variable. That is not the case in this study.
Rationale 4: The study contains all three elements of experimental design: (1) manipulation of an independent variable, (2) control/comparison group, and (3) random assignment of subjects to groups.
