2/22 Random Sampling & Ch. 8 Closure

1.  Warm-up:  Angle Challenge! On side whiteboard

2.  Creating a Random Sample

Random Samples are the BEST way to produce an unbiased, representative sample because all members of the population are equally likely to be chosen.

• Brainstorm:  You are given a list of all members of a population.  What method could you use to randomly select a sample?
• Make a list of at least 3 methods

Your team will be given the rest of the period to prepare your random sample and any materials you will need to conduct your survey.

Ideas to consider:

1. Produce a random sample
2. Divide and conquer- each member of your team should survey roughly an equal amount of people
3. Prepare materials- T-chart for data collection, Google Form/Sheet, paper survey, etc.

On Friday, your team will be given time in class to work on your report.  All surveying/data collection should be completed by 3rd period on Friday.
