What is "Sample Size"? A sample size is a part of sample size the population chosen for a survey or experiment. For example, you might take a survey of dog owner's brand preferences. You won't want to survey all the millions of dog owners in the country (either because it's too expensive or time consuming), so you take a sample size. That may be several thousand owners. The sample size is a representation of all dog owner's brand preferences. If you choose your sample wisely, it will be a sample size given good representation. When Error can Creep in When you only survey a small sample of the population, uncertainty creeps in to your statistics. If you can only survey a certain percentage of the true population, you can never be 100% sure that your statistics are a complete and accurate representation of the population. This uncertainty is called sampling error and is usually measured by a confidence interval. For example, you might state that your results are at a 90% confidence level. That means if you were to repeat your survey over and over, 90% of the time your would get the same results. A census is where every member of a population is surveyed, not just a sample. How to Find a Sample Size in Statistics A sample is a percentage of the total population in statistics. You can use the data from a sample to make inferences about a population as a whole. For example, the standard deviation of a sample can be used to approximate the standard deviation of a population. Finding a sample size can be one of the most challenging tasks in statistics and depends upon many factors including the size of your original population.
