IEOC Probability and Statistics Content Coverage

Interactive released itemsInteractive released itemsPrint-ready released itemsPrint-ready released items

The Iowa End-of-Course assessments are designed to assess student knowledge and skills in a variety of subject areas. The modules are designed to cover specific subject areas and are intended to allow for a broader coverage of content than the regular IEOC assessments. The modules consist of approximately 16 multiple-choice items and are designed to be administered in less than a single class period. The test items, which are aligned to the Common Core State Standards, reflect educator input and a rigorous quality-control process to ensure appropriateness, content accuracy, and clarity.

A summary of the content covered within the Probability & Statistics module is presented below.

Statistics and Probability
Interpreting Categorical and Quantitative Data

Topics may include summarizing, representing, and interpreting data on a single variable or on two variables and interpreting linear models, including representing the slope and intercept within the context of the data; determining the correlation coefficient of a linear fit; and distinguishing between correlation and causation.

Making Inferences and Justifying Conclusions

Topics may include understanding and evaluating random processes and underlying statistical experiments and making inferences and justifying conclusions from sample surveys, experiments, and observational studies.

Conditional Probability and the Rules of Probability

Topics may include understanding independence and conditional probability and using them to interpret data and using the rules of probability to compute probabilities of compound events and solve problems.
