Different Types of Sampling Errors Surveying an entire population is expensive and time-consuming, so researchers rely on sampling, or surveying a representative portion of the population. However, because this means that conclusions are necessarily drawn from only part of the whole population, it is always possible for errors to arise during sampling in market research . Here we'll examine four different types of errors that can occur in sampling. Sampling Error This error occurs when you draw conclusions about the larger group based on the sample you've surveyed. Most surveys have margin of error (see below) that reflects the potential for sampling error. If your survey programming and hosting has a +/-3% margin of error, it means there's a 95% chance your "true" results would fall within 3 percentage points of the reported results if you surveyed the entire population. When there is a greater chance of drawing conclusions about smaller groups, sampling error be...
