Randomization is crucial in probability sampling as it ensures that every member of the population has an equal chance of being selected for the sample. This helps to reduce bias and increase the representativeness of the sample. Using standardized questions and studying populations with normally distributed mortality rates may also be important, but they are not as crucial as using randomization to select the sample. Getting a larger sample may increase precision, but it is not the most important factor in achieving a representative sample.
