• Which of the following are examples of sampling bias? Select all that apply.
• A plan for obtaining a sample from a population is called
• In sampling without replacement, an element can be chosen
• Which one of the following is the main problem with using non-probability sampling techniques?

The important points about Sampling and Sampling Distributions are:

• The shape of the sampling distribution depends on the underlying population distribution, the statistic being calculated (mean, median, etc.), and the sample size.
• Larger sample sizes tend to produce sampling distributions that are more normally distributed (bell-shaped and symetrical), regardless of the population distribution due to the Central Limit Theorem.
• The sampling distribution is used to make inferences about the population from which the sample was drawn. For example, we can estimate the population mean by looking at the average of the sample means from many samples.

By understanding the concepts and theories about sampling and sampling distributions, one can make informed decisions based on the data collected from samples, even though one can not easily study the entire population.
