This Instructional Activity is a part of the Lesson 12, Unit 8, Grade 7. In this activity, students are asked to compare two groups (length of preferred names and last names) by collecting data from the class. They are asked if the data from the class gives enough information to draw a conclusion about a larger group. In the following activities, students will be introduced to the idea of sampling. This activity gives students the first chance to experience why sampling might be needed.
