Competency 4—Knowledge of probability, statistics, and data interpretation

Analyze data presented in various forms (e.g., histograms, bar graphs, circle graphs, pictographs, line plots, tables) to solve problems.

Analyze and evaluate how the presentation of data can lead to different or inappropriate interpretations in the context of a realworld situation.

Calculate range, mean, median, and mode of data sets.

Interpret the meaning of measures of central tendency (i.e., mean, median, mode) and dispersion (i.e., range, standard deviation) in the context of a realworld situation.

Analyze and evaluate how the selection of statistics (e.g., mean, median, mode) can lead to different or inappropriate interpretations in the context of a realworld situation.

Solve and interpret realworld problems involving probability using counting procedures, tables, and tree diagrams.

Infer and analyze conclusions from sample surveys, experiments, and observational studies.
