Using the SEER-MHOS Sample Size Estimator

SEER-MHOS Sample Size Estimator is a web tool able to estimate the number of MHOS respondents that match your cohort selection criteria. The Sample Size Estimator helps investigators generate sample size estimates for SEER-MHOS projects, allowing for tailoring by cancer site, survey timing, and Medicare enrollment.

The SEER-MHOS Sample Size Estimator is a filter. It includes all survey records in the database. Your choices of specific variables and values determine which survey records will be used for sample size estimate at the person-level. Each participant is only counted once in the Sample Size Estimator.

Please note: the SEER-MHOS Sample Size Estimator provides only a rough estimate, actual sample size may differ. In accordance with the SEER-MHOS Data Use Agreement (DUA) cell sizes less than 11 (eleven) are suppressed. Additionally, sample sizes are randomly adjusted within a +/- 10 threshold per query. Cancer site is limited to first primary cancers ONLY. (SEER Cancer Sequence number= 00 or 01)
