- All cases, labels, numbers and rules are supplied on this page. No real account, private information or purchase is needed.
Learn the idea
A data format tells how to record values consistently. Different spellings can split one category into several apparent groups. A dictionary or key can define allowed values. Our lesson uses a tiny codebook so a learner can normalize categories without guessing missing information.
Use the supplied codebook to map recognized forms into one allowed value. Standardizing a known spelling is different from inventing an unknown value.
Use this supplied case: Entry r. Codebook: red/r=RED; blue/b=BLUE; blank=?; anything else=CHECK. Normalize the supplied entry. Use the details in this example. Say which detail helped you choose. This pretend example does not tell us how every real system works.
- Follow the worked example one step at a time. Say or draw what happens.
- Use the supplied codebook to map recognized forms into one allowed value.
- Say which detail makes the example answer fit. Pick another answer and say why it does not fit.
- Try the question and practice questions. Read the rule again if your answer does not match the explanation.

Entry r. Codebook: red/r=RED; blue/b=BLUE; blank=?; anything else=CHECK. Normalize the supplied entry. The supported answer is RED. Use the supplied codebook to map recognized forms into one allowed value. Standardizing a known spelling is different from inventing an unknown value. A data format tells how to record values consistently. The supplied facts, rather than an assumed real-world detail, determine this paper case. Compare the recorded action or value with the stated rule before choosing an answer.

BLUE
The supplied case states: Entry blue. Codebook: red/r=RED; blue/b=BLUE; blank=?; anything else=CHECK. Normalize the supplied entry. Under the stated distinction, this identifies BLUE. A data format tells how to record values consistently. Different spellings can split one category into several apparent groups. A dictionary or key can define allowed values. Our lesson uses a tiny codebook so a learner can normalize categories without guessing missing information. Use the supplied codebook to map recognized forms into one allowed value.

New codebook: w/wood→WOOD, p/plastic→PLASTIC, blank→?. Expected: w normalizes to WOOD and blank remains unknown.
