# Random Samples

Videos and lessons to help Grade 7 students 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.

Common Core: 7.SP.1
