Introduction — Economics STD 11 Commerce — Question

By manipulating data, one can prove or disprove anything. Therefore, it is rightly said that there are three lies, lie, damn lie and statistics. If we start presenting data, we can prove that during 1950-1990, India made great achievements and we can also present facts in a way which will prove that we could not achieve anything during this period.
Here are some examples to show how statistics are misused.

1. 50% girls of this college marry the lecturers of the college. (There were two girls, one of them married college lecturer).
2. My result has been 100%. (Lady claiming so taught only one student).
3. Company's A's profits are double than company B's Profits. (in absolute terms they are but comparison is to be made in percentage and according to that company B's performance is better.) Therefore, one should have an expert knowledge to derive meaning of statistical statements and be cautious before relying on them.
