AAniket Yadav7 Aug 2022

Project 2

Aim:-Once a student is passed out from a Institute or College, he/she is known as Alumni of the Institute. Alumni’s career growth plays important role in Institute’s ranking and other networking activities. In this project, career choices of alumni of two Universities will be analyzed with respect to their passing year as well as the course they completed.

Dataset: Six .csv file (Alumni record of College A and College B) Higher Studies, Self Employed and Service/Job record

  • College_A_HS ~ Higher Studies Record of College A
  • College_A_SE ~ Self Employed Record of College A
  • College_A_SJ ~ Service/Job Record of College A
  • College_B_HS ~ Higher Studies Record of College B
  • College_B_SE ~ Higher Studies Record of College B
  • College_B_SJ ~ Higher Studies Record of College B
