Gramener’s Mukul Taneja was analysing data of online courses offered by MIT (Massachusetts Institute of Technology) & Harvard & he stumbled upon this – In 2015, for the online Computer Science courses, Harvard had 300K students against MIT’s 250K despite MIT having 9 courses and Harvard having just one (CS50 handled by Prof David Malan).
The Institute for Financial Management and Research (IFMR) recently interviewed S Anand, Gramener’s Chief Data Scientist on data visualization, art and public data.
Yesterday, we saw how CBSE English marks were moderated upwards and downwards. Let’s extend our data forensics into Karnataka’s state board exams in class 10 and look for patterns.
A few obvious points stand out. Firstly, a huge number of students get exactly 30 marks. This is not surprising, as 30 is the pass mark. We also observe that very few students get between 20 – 29 marks. Presumably, they are being pushed up, or “moderated” to pass the exam.
This happened in the CBSE Class XII English exam last year too – where no student “just failed”, i.e. failed within 7 marks of the pass mark.
However. that is not the case with the Karnataka English exams. A handful of students (124 in number) were among the extremely few that failed with 20 – 29 marks. Of these students, 72 could have passed if only they received the same consideration. Here are some of those students’ marks. (Each row shows the marks of one student.)
It seems a trifle unfortunate – these students would have passed if they had been given the same consideration that over 1.2 lakh students had been given, by bumping their marks up to the pass mark.
We are not sure how the policy of moderation is administered. However, it does have to be a little more consistent to avoid unfairness.
Note: We have chosen the Karnataka English exams at random. This is true of most subjects in many states, where moderation is implemented with varying levels of consistency.
