CCDM Exam Dumps : Certified Clinical Data Manager

A completedata element definitionin clinical data management should include:

Nameandclear descriptionof the data element,

Data type(e.g., numeric, text, date),

Precisionor scale (if numeric), and

Unit or dimensionalityof measure (e.g., centimeters, inches).

In this example, while the data type (“measured physical quantity”) and precision (0.1) are defined, theunit of measurement(e.g., centimeters or inches) is missing. This omission leads to ambiguity and could cause serious discrepancies when comparing or analyzing measurements.

TheGCDMP (Chapter: Database Design and Build)emphasizes that units and dimensionality must be explicitly defined and consistently applied in all CRFs, metadata dictionaries, and data transformations.

Thus,option D (Unit or dimensionality of measure)is correct.

TheScope of Work (SOW)is a project management document that defineswhat services are includedin the work agreement between the sponsor and the CRO or vendor. It outlines deliverables, responsibilities, timelines, and budget allocations.

According to theGCDMP (Chapter: Project Management in Data Management), the SOW includes specifications such as:

The number and frequency ofdata transfers,

Database build and lockmilestones,

Quality control deliverables, and

Resource allocationfor data management tasks.

The SOW does not cover operational site-level details such as monitoring schedules (B), protocol sampling details (C), or personnel contact lists (D).

Therefore,option A (number of data transfers budgeted for a project)correctly identifies a use case directly addressed in the SOW.

In arandomized, double-blind, placebo-controlled study, if statistical analysis shows that theplacebo appears to outperform the investigational product, a likely cause is adata management or coding error, particularly intreatment code entry or mapping.

According to theGCDMP (Chapter: Database Design and Build), treatment assignment data — typically stored in randomization or code-break files — must beaccurately integratedinto the clinical database. Any mismatch between randomization codes, subject identifiers, or treatment arms can lead to incorrect grouping during analysis, producing false conclusions such as placebo superiority.

The Data Manager should initiate aroot cause reviewof randomization data integration and treatment mapping. The placebo is never designed to have active medicinal effects (option A). Option D is incorrect because the described scenario implies a data inconsistency, not true efficacy differences. Proper verification of randomization coding and reconciliation between data management and statistical programming systems are essential.
