You are not alone: a table may appear organized while providing no explanation of its source, collection period, measurement units, or recording rules. Without this context, similar measures may represent different concepts, while comparisons may rely on incompatible conditions. Further difficulties arise after a table has been edited when changes, exclusions, and assumptions have not been documented. Origin Deck treats data origin as a distinct part of the analytical process.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003e2.

You will learn how to prepare a data profile describing fields, periods, categories, and measurement units. The materials explain how to compare sources, identify differences in collection methods, and document changes made during preparation. You will also learn to separate original records, working versions, and final summary tables. The concluding assignment involves preparing a complete documentation package for a learning analysis.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003e3.
