Part b):
What are the types of sampling design? Explain each type.Types of sampling design in Research Methodology
There are different types of sample designs based on two factors viz., the representation basis and the element selection technique. On the representation basis, the sample may be probability sampling or it may be nonprobability sampling. Probability sampling is based on the concept of random selection, whereas nonprobability sampling is ‘nonrandom’ sampling. On element selection basis, the sample may be either unrestricted or restricted. When each sample element is drawn individually from the population at large, then the sample so drawn is known as ‘unrestricted sample’, whereas all other forms of sampling are covered under the term ‘restricted sampling’. The following chart exhibits the sample designs as explained above.
Thus, sample designs are basically of two types viz.,
 Nonprobability sampling
 Probability sampling.
We take up these two designs separately.

Part a):
What is the difference between Random Sampling with and without replacement?In sampling without replacement, each sample unit of the population has only one chance to be selected in the sample. For example, if one draws a simple random sample such that no unit occurs more than one time in the sample, the sample is drawn without replacement.
