Method of Data Analysis

&nbsp.In such a case, a researcher can ask students to report the number of hours spent studying for exams.
The researcher may employ a correlation measure that may help to determine the relationship between study hours variable and score in exam variable. In such a case, a negative correlation in the analysis would indicate that studying relates to a lower score. The measure of dispersion will not work well for the type of data since the intention of the research is not to find spread or clusters of data.
