Algebra 2 (& GT)
Unit 7: Inferences and Conclusions from Data
What will my child learn?
Students will:
Summarize, represent, and interpret data on a single count or measurement variable.
S.ID.A.4
Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.
Understand and evaluate random processes underlying statistical experiments.
S.IC.A.1
Understand statistics as a process for making inferences about population parameters based on a random sample from that population (SAT® Content - PSDA.08).
Make inferences and justify conclusions from sample surveys, experiments, and observational studies.
S.IC.B.3
Recognize the purposes of and differences among sample surveys; explain how randomization relates to each (SAT® Content - PSDA.10).
Understand and evaluate random processes underlying statistical experiments.
S.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.
S.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.
S.IC.B.5
Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.
S.IC.B.6
Evaluate reports based on data (SAT® Content - PSDA.10).
Students will:
Summarize, represent, and interpret data on a single count or measurement variable.
S.ID.A.4
Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.
