Often, students or employees will be asked to draw a conclusion from a huge amount of datA、That’s when a sample is introduceD、When a sample is accurate, it can represent the whole group.But when it is wrong, sampling error would occur. In statistics, sampling error or estimation error is caused by observing a single sample instead of the whole population. Sampling error can be found by subtracting the value of a parameter from the value of a statistiC、Generally, there are two methods of reducing sampling error: increasing the sample size, and ensuring that the sample can adequately represent the entire population.
