Final answer:
In psychological research, a carefully regulated procedure where the researcher manipulates one or more variables thought to influence something else is called an experiment. Here, the impact of the independent variable on the dependent variable is measured. For example, the effect of a new tutoring system on student test scores.
Step-by-step explanation:
In the context of psychological research methods, a carefully regulated procedure in which the researcher manipulates one or more variables that are believed to influence some other variable is referred to as experiments.
During experiments, the independent variable is manipulated by the researcher and the effects on the dependent variable are observed and measured. The goal is to determine if a cause-and-effect relationship exists.
For example, a researcher might want to understand the effect of a new tutoring program (independent variable) on students' test scores (dependent variable). The tutor may assign half of a class to receive the new tutoring program while the other half does not. The control group in this instance would not receive the new tutoring program. Thus, any changes seen in the test scores can then be attributed to the impact of the tutoring program.
