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"..
Expected mean of each option=np=66*1/5=13.2
Variance=npq=66*1/5*4/5=10.56
Standard dev.=3.25
GR0568:
"A"---11
"B"---14
"C"---11
"D"---16
"E"---14
GR9768:
"A"---11
"B"---13
"C"---13
"D"---16
"E"---13
GR9367:
"D"---17
GR8767 (anomaly):
"D"---13
Higher percentage of option D ??
