Simple random sampling is the most basic and common type ofsampling methodused in quantitative social science research and in scientific research generally.The main benefit of the simple random sample is that each member of the population has an equal chance of being chosen for the study. This m...
In order to answer the research questions, it is doubtful that researcher should be able to collect data from all cases. Thus, there is a need to select a sample. This paper presents the steps to go through to conduct sampling. Furthermore, as there are different types of sampling techniqu...
Sincesimple random samplingof a population can be inefficient and time-consuming, statisticians turn to other methods, such as systematic sampling. Choosing a sample size through a systematic approach can be done quickly. Once a fixed starting point has been identified, a constant interval is select...

How to avoid:You should try random sampling to minimize the occurrence of such sampling errors. FUN FACT How to avoid:You should try random sampling to minimize the occurrence of such sampling errors. One of the most popular sample frame errors occurred during the presidential election 1936 in ...
1. Issues with research samples and selection Sampling errors occur when a probability sampling method is used to select a sample, but that sample does not reflect the general population or appropriate population concerned. This results in limitations of your study known as “sample bias” or “...
It is best used for testing as part of hypothesis generation, getting a ‘sense’ of opinions or as an initial pilot before further research. Don’t mistake this for random sampling, because of how people can be stopped at random by the researcher. It is also unlike probability sampling, ...
An alternative method, which makes use of random sampling and which is also designed to retain key structures in the point cloud, is the dart throwing filter [136], where points from the original point cloud are sequentially added to the downsampled point cloud if they don’t have a neighbo...
