This is the second lesson in the Experimental Design Unit. Students are introduced to key vocabulary terms. They will identify the population and sample of a statistical study. They will identify voluntary and convenience sampling techniques which lead to bias results. They will explain how they produced biased data. Students will describe how to do an SRS with technology, slips of paper, and random digits. They will also describe how to take a stratified, cluster, and systematic sample. They will identify the advantages to certain sampling techniques. This lesson is designed for the teacher to lead the students through the note-taking process while providing examples along the way for the students to try. Answers are included with pages numbered.
