MAFS.912.S-IC.2.3 – Recognize the purposes of and differences among sample surveys, experiments, and observational studies and explain how randomization relates to each..

  1. The benchmark will be assessed using Equation Response, Multiple choice Response, Open Response or Simulation Response.
  2. Items may require students to use data from a sample survey to estimate a population mean of proportion; develop a margin of error through the use of simulation models for random sampling.
  3. Items may require students to use data from a randomized experiment to compare two treatments.
  4. Items may require students to choose and interpret units.

Example One

For a statistics project, a group of students decide to collect data in order to approximate the percent of people in the town who are left-handed.  They ask every third student entering the school cafeteria whether he or she is left-handed or right-handed.  What type of method did this group use?  Explain which population the group can draw a conclusion about based on their method.  Suggest a better method that would allow the students to draw a conclusion about all the residents in their town.
