• Coverage error, which refers to drawing samples form a list of irrelevant samples to represent the population.
• Sampling error, which exists any time when the researcher reaches some of the sample and not all members. 
• Nonresponse error, which occurs when some particular units of analysis tend to answer some particular items which are likely to influence the estimate of the findings.
• Measurement error is described as the difference between the estimate produced and the true value in case the respondents may answer inaccurately to the survey questions.
