Question

mention the name of two random numbers tables used to draw random sample​

Answer 1

There are a variety of different types of sampling techniques. Of all statistical samples, the simple random sample is indeed the gold standard. In this article, we will see how to use a table of random digits to construct a simple random sample.A simple random sample is characterized by two properties, which we state below:

Every individual in the population is equally likely to be chosen for the sample

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 that it is important to have a process to obtain such a sample. We must have a reliable way to produce randomness.

While computers will generate so-called random numbers, these are actually pseudorandom. 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. The following example goes through a detailed sample calculation. By reading through this example we can see how to construct a simple random sample with the use of a table of random digits
