#### Maryland College and Career-Ready Standards

MD.MA.AI. Algebra I
Unit 3: Descriptive Statistics
HSS-ID.A. Summarize, represent, and interpret data on a single count or measurement variable.
S.ID.2. Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
S.ID.2.1. Ability to interpret measures of center and spread (variability) as they relate to several data sets.
S.ID.3. Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).
S.ID.3.1. Ability to recognize gaps, clusters, and trends in the data set.
MD.MA.AII. Algebra II
Unit 4: Inferences and Conclusions from Data
HSS-IC.A. Understand and evaluate random processes underlying statistical experiments.
S.IC.1. Understand statistics as a process for making inferences about population parameters based on a random sample from that population.
S.IC.1.1. Knowledge of various sampling methods (e.g., simple random, convenience, stratified…).
S.IC.1.2. Ability to select an appropriate sampling technique for a given situation.
S.IC.1.3. Ability to explain in context the difference between values describing a population and a sample.
S.IC.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?
S.IC.2.2. Knowledge of various types of sampling procedures and ability to select and carry out the appropriate process for a given situation.
HSS-IC.B. Make inferences and justify conclusions from sample surveys, experiments, and observational studies.
S.IC.3. Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each.
S.IC.3.1. Ability to conduct sample surveys, experiments and observational studies.
S.IC.5. Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.
S.IC.5.1. Ability to set up and conduct a randomized experiment or investigation, collect data and interpret the results.
Unit 5: Applications of Probability
HSS-MD.A. Use probability to evaluate outcomes of decisions.
S.MD.7. (+) Analyze decisions and strategies using probability concepts (e.g., product testing, medical testing, pulling a hockey goalie at the end of a game).
S.MD.7.2. Knowledge of and ability to use a variety of data collection techniques.
