Previous Step Next Protocol Translation and CRF Design Data Dictionaries and Metadata Knowledge Check 30-45 minutes Foundational Step 5 of 5 Flip Cards Knowledge Check 5 / 5 Flip Cards Knowledge Check Listen What is metadata? Information that describes and provides context about data Define a data dictionary? A structured document or metadata resource that defines and describes the variables and associated attributes within a dataset or database. What is the relationship between a CRF and a data dictionary? The CRF shows what users enter, while the data dictionary defines how the data are structured and represented Which metadata attribute specifies whether a variable is text, numeric, date, or another format? Data type A data dictionary states that visit_date must follow YYYY-MM-DD format. What type of metadata is this? Validation A clinical trial database contains: bp1 = 120, bp2 = 80 The data manager knows these are blood pressure measurements, but the dataset contains no labels, units, definitions, visit information, or indication of whether the values represent systolic or diastolic measurements. Identify at least five pieces of metadata that should be documented. Variable name, Variable label, Systolic vs. diastolic designation, Unit of measurement, Data type, Validation range, visit date Why should coding standards be documented? To ensure that data values are represented and interpreted consistently across participants, sites, databases, and analyses. Previous Step Log in to track progress Next Lesson
