Big Ideas: The population is the entire group being studied and a sample is part of the population being surveyed. Random sampling tends to produce representative samples and support valid inferences. In this lesson, students will engage in a scenario that they are familiar with in a middle school setting. Students will develop a survey method that allows data collection for a random sampling of students in a middle school environment. Along with the development of the survey, students must evaluate whether or not the developed survey will produce a representative sample and support valid inferences. Vocabulary: random, sample, population, inference, bias, survey
