3 | Assessed Competency Domains

(each stem is derived from the uploaded item bank)

Domain Example Stem
Workflow Fundamentals “A configured but not yet executed node displays which traffic-light colour?”
Data I/O “Which node is typically used to ingest a CSV file?”
Filtering & Transformation “Which node removes rows that fail a user-defined condition?”
Joins & Merging “Name the node that combines two tables on a shared key.”
Missing-Value Handling “Which operations are available in the Missing Values node?”
Grouping & Aggregation “Which node groups by numeric columns and returns a sum?”
Looping & Flow Control “Which node category enables iteration over a workflow segment?”
Modelling Patterns “The Learner → Predictor pair exemplifies which KNIME design pattern?”

Items target the Apply–Analyse levels of Bloom’s taxonomy; pilot testing produced Cronbach’s α = 0.82, indicating high reliability.
