*My research question was,"Are exam averages correlated with student final exam scores.

*The explanatory variable was the exam average, and the response variable was final exam scores.

*The correlation coefficient shows that there is a positive linear association between exam average and final exam scores. If we look at our plot we can see the shape of the graph moving upward as we go to the right. 

*If we look at our correlation coeffiecient we can see that it is .885, that number is pretty close to one which can help us see that there is a positive relationship there. This can help us answer our research question and say that exam averages are positively correlated with final exam scores.

*Some lurking variables might be the skill level and knowledge of students, if some students get the concept and are advanced in the subject their scores only correlate because they will do good in both type of exams.
