Benefits of audit sampling include reducing the cost and time of the audit, providing reasonable assurance, and complying with auditing standards. Random sampling is considered as a systematic and most scientific means of studying the population. Sampling error, and lack of representation of population make it harder for the researchers to generalise the results of their study to the population as whole.

One strength of the Crab Team protocol is that it enables us to confidently compare findings among different sites, and track changes over time - even if different people are doing the sampling. Because of the processes that allow for random sampling, the data collected can produce results for the larger frame because there is such little relevance of bias within the findings. Facebook polls or questions can be mentioned as a popular example for convenience sampling. The application of random sampling is only effective when all potential respondents are included within the large sampling frame. Convenience sampling. This helps to create more accuracy within the data collected because everyone and everything has a 50/50 opportunity. Examples of convenience sampling Judgement sampling is where the auditor using his own experience and knowledge of the client's business and circumstances selects the sample to be tested without use of any mathematical or statistical tools. It is also considered a fair way to select a sample from a population, since each member has equal opportunities to be selected. Excel) - Systematic selection (uses sampling interval - eg. Nonstatistical sampling relies more on the auditor's judgment. 2. Therefore, the advantages and disadvantages of convenience sampling are the reverse of probability sampling. disadvantages of haphazard sampling Purposive sampling becomes useful in this situation, because it offers a wide selection of non-probability sampling techniques. There are 2 general approaches to sampling: statistical sampling and nonstatistical sampling. Scope of sampling is high. when you have a very small population to work with).

Lecture Seven - Sampling final.ppt - Lecture seven Audit This sampling technique needs little planning and fewer workforce compared to other sampling techniques. Non-Probability Sampling: Nonprobability Sample a particular member of the population being chosen is unknown. Multiple types of randomness can be included to reduce researcher bias. ISA 530 recognises that sampling risk can lead to two types of erroneous conclusion: Non-sampling risk is the risk that the auditor forms the wrong conclusion, which is unrelated to sampling risk. A Sample is a little extent of a population. 5. time sampling advantages and disadvantages. Haphazard sampling is a sampling method in which the auditor does not intend to employ a systematic approach to selecting a sample. We can divide nonprobability sampling methods into two broad types: accidental or purposive.

It may not be as accurate as auditing the entire population. The information you receive from a convenience sample doesn't reflect the way a generalized population group feels about anything specific.
