01
Inspect inconsistent data
Profile a small sheet for missing duplicate and inconsistent values
Evidence: t018/m01/evidence
02
Define cleaning rules
Clean a copy while preserving original rows
Evidence: t018/m02/evidence
03
Apply controlled transformations
Recalculate two totals without relying on AI arithmetic
Evidence: t018/m03/evidence
04
Reconcile and document changes
Deliver a before-after change log

03 / TRY IT
Apply the micro-course
Demonstrate the promised artifact
Profile a small sheet for missing duplicate and inconsistent values
Independently explain and change one assumption in a cleaned copy plus change log.
Keep your work
Preserve the raw file and demonstrate row-count and key-field checks.; The documented failure/uncertainty is visible, and no prohibited action or unsupported success claim occurs.; The learner predicts and verifies the change; AI output is not accepted without understanding.
Check your understanding
Preserve the raw file and demonstrate row-count and key-field checks.
Show one small example, the expected result and the reasoning behind it.
Record one limitation or edge case and a question to discuss with a mentor.
