Essential Understandings
Concrete:
- Given a classroom, put all of the student names in a hat. The hat with all of the names in it represents the population. Randomly choosing names out of the hat represents a random sample.
- Given a classroom in the school, determine the range of ages in the classroom. Use the data to approximate the range of ages in a school or grade level.
- Understand that statistics is collecting, organizing, analyzing, and interpreting data in order to make decisions.
- Understand that mean, median, mode, range, and standard deviation are common statistics.
- Understand that each item/subject in a random sample has the same chance of being selected.
- Understand that generalizations are only valid if they are based on similar characteristics in both the sample and the population.
- Understand that decisions about the population can be made based on the information gathered from the random sample.

Cluster:
Make inferences and justify conclusions from sample surveys, experiments, and observational studies. (Algebra 2 - Major Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
