### About the Lesson

At times, it is a challenge to analyze the entire population, the whole group from which you may collect data. When this happens, taking a sample, a small group chosen from the population, of the data would be an easier approach. Students will explore questions that provide real world examples ,where students will be discussing and using the following sampling techniques:

• simple random sample
• systematic sample
• convenience sample
• biased sample
• quota sample
• stratified sample
