Final answer:
The operational definition in the provided research example describes specific measurable criteria for terms like "good" grade and "tutoring" for consistency in data collection and study replicability, highlighting the fundamental role of operational definitions in practicing the scientific method.
Step-by-step explanation:
In the research example provided, the operational definition is used to illustrate the scientific method by specifying what is meant by terms like "good" grade and "tutoring." These definitions are crucial as they provide a clear, measurable way to identify and assess the variables in the study. For instance, by stating that a "good" grade may be a C or better, or a B+ and above, and defining "tutoring" as "one-on-one assistance by an expert in the field, hired by an educational institution," researchers can create a standardized way to collect data and ensure that their study can be replicated consistently by others. This clear definition is essential for making scientific inquiry systematic and reproducible as well as for ensuring that the results are interpreted correctly by others. The use of the scientific method in sociological research follows similar guidelines by starting with clear operational definitions, followed by making observations, forming hypotheses, designing controlled experiments, and then analyzing the data to draw conclusions. This sequence helps in ensuring that sociological research is conducted in a methodical and replicable manner.
