• 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.

Sampling error

_______ ________ also occurs with non-probability and, because of lack of randomization, sampling bias is likely

sampling error

We want the sampling frame to include ___________ in the population

everyone!

What happens when the sampling frame doesn't dhow everyone in the population?

non-representative probability samples are possible because those not in sampling frame may differ fundamentally from those in the sampling frame.
