EngageNY5 min(s)

This Instructional Activity is a part of the Lesson 17, Unit 5, Grade 7. Carefully discuss the sample directions outlined in this section. The goal is to recognize that each of the population values has an equal chance of being selected into the sample. Introduce the random number table, and as students work through this example, make sure that they understand how the table is used to identify individuals to be included in the sample. Once a sample is selected, the sample mean is calculated for this sample, and students are encouraged to think about how different samples would result in different values of the sample mean.
