SI-19(5)—Statistical Disclosure Control
>Control Description
Manipulate numerical data, contingency tables, and statistical findings so that no individual or organization is identifiable in the results of the analysis.
>Supplemental Guidance
Many types of statistical analyses can result in the disclosure of information about individuals even if only summary information is provided. For example, if a school that publishes a monthly table with the number of minority students enrolled, reports that it has 10-19 such students in January, and subsequently reports that it has 20-29 such students in March, then it can be inferred that the student who enrolled in February was a minority.
