Standard(s) Taught

#### Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.

Learning Targets and Learning Criteria

Students are successful when they can…

• determine the area of two-dimensional figures (triangles and quadrilaterals).
• determine the surface area and volume of three-dimensional figures.
• solve real-world involving area, surface area and volume.
• solve problems involving a missing dimension of a geometric figure.
• critique examples of random sampling as statistical tools using precise mathematical vocabulary: random sampling, population, and valid generalizations.
• design random samplings to collect the data given statistical questions.  Defend the samplings as random.
• draw valid inferences and generalizations from random samplings of populations and justify their inferences and generalizations as valid using appropriate vocabulary.
• explain the variability in multiple random samples and gauge how far off an estimate may be.
