Incorrect Analysis: CBSE Class XII results out, girls again outshine boys

Various apples

I just read this news article and something did not seem right, so I thought about digging further and found the CBSE detailed analysis here.

If you go through the analysis, Yes, more girls have cleared than boys BUT the correct ‘apples to apples’ comparison will be subject wise results.

Reason why the analysis is incorrect –

Say there are only 2 subjects Chemistry and Home Science. 100 students write the exam (ie 50 boys and 50 girls).

Now lets say 40 boys opt for Chemistry and 10 boys opt for home science. Similarly 10 girls opt for chemistry and 40 girls opt for Home science.

Let the pass % in Chemistry is 85% for boys and 80% for girls and similarly the pass % is 97% for boys and 96% for girls in Home science.

In aggregate (chemistry + home science) 43 boys have passed and 46 girls have passed. But subject wise, the pass % of girls is lower. Is it correct to state that the girls have outperformed boys, when in both the subjects boys have performed better?

Therefore, Apples to Apples comparison is required.

Let’s see the data of the highest pass % subjects in the exam –

  • Home Science
  • Political Science
  • Sanskrit
  • Sociology
  • Urdu
  • Geography
  • Hindi
  • History

Now do let me know which subjects are taken up by majority of the girls?

CBSE needs to provide subject wise pass percentage of boys and girls for the analysis to be meaningful.
