Question

The binomial distribution is symmetrical _________.
A) for all values of P and Q
B) only when P = Q = .50
C) for N > 8
D) for P > Q

Quizplus · Accepted Answer

The binomial distribution is symmetric only when P = Q = .50. When P and Q are not equal, the distribution is skewed towards the side with the higher probability. As N becomes larger, the distribution may become more nearly symmetric, but it will only be truly symmetric if P = Q = .50.
