Learning Goal
Part of: Use random sampling to draw inferences about a population — 1 of 2 cluster items
Understand that statistics can be used to gain information about a population by examining a sample
7.SP.A.1 -- Understand that statistics can be used to gain information about a population by examining a sample of the population; understand that 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.
