In trying to estimate the variability in the population in order to determine pq, which of the following represents viable alternatives?
A) use a random number generator to provide two random values for p and q
B) use the most conservative approach, p = 10, q = 90
C) use 90/10 OR find a former study and calculate the variance OR conduct a pilot study
D) use 1/5 OR find a former study and calculate the variance OR conduct a pilot study
E) use 50/50 OR find a former study and calculate the variance OR conduct a pilot study

Using 50/50 is the most conservative estimate for maximum variability, and finding a former study or conducting a pilot study are valid methods to estimate variability.
