# Algebra II Making Inferences and Justifying Conclusions

#### Resources

Understand and evaluate random processes underlying statistical experiments.
HSS-IC.A.1. Understand statistics as a process for making inferences to be made about population parameters based on a random sample from that population.
HSS-IC.A.2. Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation. For example, a model says a spinning coin falls heads up with probability 0.5. Would a result of 5 tails in a row cause you to question the model?
Make inferences and justify conclusions from sample surveys, experiments, and observational studies.
HSS-IC.B.3. Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each.
HSS-IC.B.4. Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.
HSS-IC.B.5. Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.
HSS-IC.B.6. Evaluate reports based on data.
