In stratified sampling the strata are prepared and according to proportion sample is selected, similarly in quota sampling data are divided into different quotas and sample is taken. This is a strong representative of the population while their cost is more and it consumes more time for the study and the report is submitted in the long time to concerned department while the non-probability sampling techniques are not the good representative of the population but its cost and time is less and in time the research is processed and report is submitted. The probability sampling technique is a successful sample selection technique, and there is a fair chance of sample selection for all members of the population. All the mentioned sampling techniques are used for different purpose.

Sampling has two main form, Probability Sampling and non-probability sampling, and the full population list is required in probability sampling while non-probability sampling the list of population is not required for the sampling process. The sampling and assignment of the sampling method is essential in cases where the researcher is unable to count because of the time constraints and cost. Research is a systematic and objective attempt to study the problem for finding the solution. Keywords: stratified sampling, quota sampling, sampling of non-probability, probability sampling Introduction However, it disguises potentially significant bias. Quota sampling is therefore primarily used by market analysts rather than stratified sampling, as it is mostly cost-effective and easy to conduct and has the appealing equity of satisfying population reach. More specifically, stratified sampling is a method of probability sampling which enables the calculation of the sampling error. For stratified sampling, a sampling frame is necessary, but not needed for quota sampling. Stratified sampling uses simple random sampling when the categories are generated sampling of the quota uses sampling of availability. The main goal of both methods is to select a representative sample and facilitate sub-group research. Both require the division into groups of the target population. Quota sampling and Stratified sampling are close to each other. The pair shows the differences and similarities between them, different articles were reviewed to compare the two. In this paper we studied the differences and similarities of the two with approach that is more of fritter away time, cost sufficient with energy required throughout the sample observed. There is a need therefore, this article provides a probability and non-probability sampling. The possibility that researchers should be able to obtain data from all cases is questionable.
