Abstract

IBS faculty members G V Muralidhara and G Vijayudu decided to improve the attitude of the BBA students. The students were asked to give a presentation on the ‘Importance of Attitude’. The faculty members made the students responsible for grading each other. The collected grading data was given to Muthukumar, analyst, for analysis. This case study enables us to understand and analyze the gathered data to identify the highest graded student and compare each student’s grading with the overall class’s grading.
