Internal marks
Externalmarks Scatterplot of External marks vs Internal marks
Pearson Correlation in between External marks and Internal marks is 0.761
It implies Internal marks secured by students are strongly influencing the
performance in end semester exams. Hence “Internal Criteria of giving Marks” is
highly related with External result. It must be optimized (factors affecting
external result more, should have high weightages in terms of marks) to further
lure and motivate the students for good result in External exams…..
