• Review Test 3

Objectives

• Identify the population and sample in a statistical study.
• Identify voluntary response samples and convenience samples. Explain how these sampling methods can lead to bias.
• Describe how to obtain a random sample using slips of paper, technology, or a table of random digits.
•  Distinguish a simple random sample from a stratified random sample or cluster sample. Give the advantages and disadvantages of each sampling method.
• Explain how undercoverage, nonresponse, question wording, and other aspects of a sample survey can lead to bias.

Agenda

  • Simple Random Sample
  • Stratified
  • Systematic
  • Convenience/Volunteer
  • Mulitstage sample
• Choose students from Seward High school (use the Excel file: here is a tutorial on random sampling in Excel video) to survey using each of these methods. Pick a sample size of 5 students of each sample type below:
• Put each of you students picked by each type in a word document and type a paragraph telling how you got each sample - (Sampling students from SHS)

•  Explain the purpose of comparison, random assignment, control, and replication in an experiment.

•  Describe a completely randomized design for an experiment, including how to randomly assign treatments using slips of paper, technology, or a table of random digits.

•  Describe the placebo effect and the purpose of blinding in an experiment.

•  Interpret the meaning of statistically significant in the context of an experiment.

•  Explain the purpose of blocking in an experiment. Describe a randomized block design or a matched pairs design for an experiment.
