Data Table Cleanup Answer Key

In this worksheet, students examine a messy dataset designed to mimic raw data used to train AI models. The dataset includes duplicate entries, inconsistent labeling, unclear categories, and formatting issues. Students analyze the dataset to identify errors, list duplicate or near-duplicate items, and determine which entries lack proper labels. They then propose rules or systems for cleaning and standardizing the data. The worksheet builds data literacy skills by teaching students how inconsistencies negatively affect AI performance and how clean, reliable datasets produce more accurate results. It reinforces attention to detail and procedural thinking.
