Why are pseudorandom numbers not random?
These pseudorandom numbers are not truly random because hiding in the background, a deterministic process was used to produce the pseudorandom number. Good tables of random digits are the result of random physical processes.
Why is simple random sampling important?
Every set of size n is equally likely of being chosen. Simple random samples are important for a number of reasons. This type of sample guards against bias. The use of a simple random sample also allows us to apply results from probability, such as the central limit theorem, to our sample. Simple random samples are so necessary ...
