Examples, solutions, worksheets, 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
Identify a random sample.
Identify a biased question.
A population is a group of objects or people. You can gain information about a population by surveying a sample, or a part of a population.
In a random sample, each member of the population has the same chance of being selected. Random sampling tends to produce samples that are representative of the entire population. Generalizations based on representative samples are more likely to be correct.
A biased question is a question that makes an unjustified assumption or makes some answers appear better than others.
