Common Core MATH 7 SP 1 Grade 7 Statistics And Probability Use Random Sampling To Draw Inferences About A Population

Statistics And Probability: Use Random Sampling To Draw Inferences About A Population.

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.
