Case Study

The number of students completing MBA has increased exponentially from under 5000 in the 60’s to over 1,00,000 by the year 2000. One of the aspects which is agitating the minds of these students is on deciding on the area of specialization which they should adopt. To study the same four variables were considered: Previous work experience affects the choice (X1), Placement of a senior affects the choice (X2), Experience with the courses and the professors in the first year affects the choice (X3) and future job prospects affects the choice (X4). Data was collected on the above four variables from randomly chosen 69 participants and the analysis of the results are given below.Data for each variable was collected using a five point scale.

An analysis of variance technique was used to analyse the data which is given below:

                                  ANOVA
