An example of a simple random sample would be to choose the names of 25 employees out of a hat from a company of 250 employees. In this case thepopulationis all 250 employees, and the sample is random because each employee has an equal chance of being chosen. Random sampling is used in...
randomsamplesimple抽样随机sampling A simple random sample of n measurements from a population is one selected in such a manner that 1. every sample of size n from the population has equal probability of being selected, and 2. every member of the population has equal probability of being include...
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...
As its name implies, producing a simple random sample is much less complicated thanother methods. There are no special skills involved in using this method, which can result in a fairly reliable outcome. This is in contrast to other sampling methods likestratified random sampling. ...

Simple Random SampleJudkins, David Ross
In simple random sampling, researchers collect data from a random subset of a population to draw conclusions about the whole population.
Lastly, this method is cheap, quick, and easy to carry out – great when you want to get your research project started quickly. Disadvantages of simple random sampling There may be cases where the random selection does not result in a truly random sample. Sampling errors may result in simila...

Second, assumptions (e.g., completely random errors, correctly specified models) are almost implausible in reality, and thus the sample size may be underestimated (Rothman et al., 2008). In addition, researchers may reduce inference to dichotomy at an arbitrary level of statistical (rather than...
