The use of p=50%,q=50% is a research industry standard at least in part because:
A)it is the most conservative p-q combination
B)it generates the largest sample size
C)it is preferred to guessing about variability
D)there may be little prior knowledge about the population to be studied
E)all of the above are true

Question

Quizplus · Accepted Answer

All of the above options are true. Using p=50% and q=50% is the most conservative option as it assumes maximum variability in the data. It also generates the largest sample size which helps to increase the precision of the estimates. Additionally, it is a preferred option when there is little prior knowledge about the population being studied, as it does not rely on any assumptions about the population.
