For example, a study on Ontario citizens’ sleeping habits would have a population equivalent to that province’s population (13.5 million). In many studies it will be impossible to know how many people make up a population. If this is the case, it is accepted among researchers to use a fake population size of 20,000 or larger. Your desired confidence level: Usually placed at a value of 95% in surveying, the confidence level describes how sure you can be that your results are correct. With a 95% confidence level, a researcher can be certain that the value of any sample will fall in the range of the margin of error 95% of the time. Your allowed margin of error: Margin of error depicts the random sampling error that is possible in the study. This is important because it is impossible to know whether a sample’s results are identical with the true value of the population. The value allotted to the margin of error describes the range in value that the population may have based o
