Final answer:
A research experiment involves conducting a study to test a specific hypothesis. By comparing the construct of a new experiment to a previous successful one, researchers can determine the effectiveness of a treatment or intervention. They need to consider the experimental design, variables, and outcomes of both experiments.
Step-by-step explanation:
In a research experiment, a researcher conducts a study to test a specific hypothesis. This involves designing and implementing a study that compares an experimental group with a control group. The goal is to gather enough data to determine the effectiveness of a particular treatment or intervention. To compare the construct of a new research experiment to a previous successful one, the researcher would need to consider the similarities and differences in the experimental design, variables being measured, and the outcomes of both experiments.
