randomization is not utilized
Explain sampling error
Error that occurs when we use a sample statistic to estimate the value of a population parameter.
Explain sampling bias
Error that occurs from using a non-probability sample or from under coverage.
What is under coverage?
Undercoverage refers to the sampling frame not capturing everyone in the target population.

Error that occurs when some sampled subjects refuse to participate or do not complete portions of the survey.
What is a response bias
Error that occurs from subjects' incorrect responses or poorly worded questionnaires.
What type of error occurs with probability sampling but due to randomization we have statical theory to guide our inferences
Sampling error
_______ ________ also occurs with non-probability and, because of lack of randomization, sampling bias is likely
sampling error
