Hill (1990) studied the correlations between final exam score in an introductory sociology course and several other variables such as number of absences. The following Pearson r correlation coefficients with final exam score were obtained:
Overall college GPA
Number of absences
Hours spent studying on weekdays
−.11 (not significant)
Hours spent studying on weekends
Describe each correlation and how graphs might depict the general shape of each relationship. Why might hours spent studying on weekends be correlated with grades but weekday studying not be?© BrainMass Inc. brainmass.com September 23, 2018, 12:30 pm ad1c9bdddf - https://brainmass.com/sociology/research-methods/pearson-r-scores-580648
Overall college GPA is positively correlated with final exam scores in an introductory sociology course. This is shown through the Pearson r score, which is .72. The closer the Pearson r score is to 1, the stronger the relationship. This means that students who have a higher overall GPA score have a higher final exam score in an introductory sociology course. A graph for this Pearson r score would be a steep line that goes from the bottom left of the graph and go steeply towards the upper right of the graph.
Number of absences is negatively correlated with final exam scores in an introductory sociology ...
This solution takes a look at a sample of Pearson r scores and what they mean.
