Higher percentage of option D ??

Postby yoyobarn » Sat Jan 28, 2012 7:48 am

Hi, recently I noticed that recent GRE practice papers seem to have more "D"s.

Is it statistically significant? If yes, I might consider "guessing D when in doubt".. :lol:

Expected mean of each option=np=66*1/5=13.2
Standard dev.=3.25
