<h3>What is a research investigation?</h3>
In science, a research investigation is an organized inquiry made into phenomena in order to logically understand them. The investigation follows an established procedure, otherwise known as the scientific method.
The original investigation by the student has to do with factors that affect math grades. Conclusions are usually drawn from the aim and objectives of the research. Thus, the conclusion must relate to the aim of the research in a logical way.
The only option that fits in logically going by the aim of the investigation is that students who spend less time studying after school, get lower math grades.
