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.
