Describe Populations and Samples

(A) Compare and contrast the benefits of different sampling techniques, including random sampling and convenience sampling methods

(Y11-12) Understand the purpose of sampling to provide an estimate of population values when a census is not used (ACMEM129)

(Y11-12) Investigate the different kinds of samples; for example, systematic samples, self-selected samples, simple random samples (ACMEM130)

(Y11-12) Investigate the advantages and disadvantages of these kinds of samples; for example, comparing simple random samples with self-selected samples (ACMEM131)

(Y11-12) Identify the target population to be surveyed (ACMEM132)

7.SP.1 Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.
