“Statistics are like a bikini. What they reveal is suggestive, but what they conceal is vital.”
It occasionally amuses me to surf mathematical websites for interesting problems. Statistical ones are a minefield of misdirection and I quite liked this one.
A company is expanding and has 455 new jobs, 70 white collar, the rest blue. For the white collar jobs there were 200 male and 200 female applicants. 15% of the men and 20% of the women were hired. For the blue collar jobs 400 men and 100 women applied. 75% of the men and 85% of the female applicants were hired.
Would anybody with a logical turn of mind like to point out the flaw in the reasoning?
Creating policy based on statistics like this is doomed to failure, whether the policy is concerned with how many new settlements to build in East Jerusalem or which school is ‘better’ based upon league tables.
