Sampling theory tells us that the way to select a sample from a larger population in order to eliminate systematic sample bias is to select the sample on the basis of chance alone (Chapter 5 in Investigating the Social World). Don't let anyone's characteristics influence whether they are selected for the sample--just leave it up to "chance."

Sampling gets at the essence of inferential statistics: to draw accurate generalizations about a . population. using a smaller . sample. Population characteristics are called . parameters. We symbolize these as Greek letters: μ, σ, π. Sample characteristics are called . sample statistics. We symbolize these as English letters., s, p. 2.

A) Too small a sample. B) Inadequately defined problem. C) Inadequate techniques of analysis. D) Biased sample. 29. The most important consideration in selecting a sample is that the sample be: A) selected from the population by means of a table of random numbers. B) made up of a large number of subjects. C) representative of the population

The Researcher’s Curse: Variation of sample statistics from sample to sample. Research involves taking samples and making decisions based on the sample results. Unfortunately, sample characteristics vary from one sample to the next. So, my decision based on a sample I took might be different from your decision based on a sample you took.
