Data and charts: integrated task
Deliver independent work with new material, compare the reference and retain revisions and acceptance evidence. Data and charts
Data and charts · 5/5
Data and chart workbench
Process a local two-column group,value CSV, up to 500 rows and 20 groups. Values must use one unit. Blanks stay missing; equal rows may be separate events. Data is not uploaded.
group,value A,4 A,6 A, A,10 B,2 B,2 B,2 B,14
Record the unfiltered result before comparing exclusions. Charts show summaries; inspect the raw CSV for distributions. Means do not represent every experience.
Independent attempt and revision
Fictional library loans: A has 2,4,4,6 and B has 1,1,2,12; each also missed one record. Produce a chart and report covering mean, median, missingness, encoding, limits and further collection. Audit this AI candidate: “Both means are four, so the services are identical.”
Reference and self-check
Both means are four; medians are four and 1.5. Bars start at zero; each group has n=4 and one missing. Loans do not establish service quality. Propose comparable collection.
AI collaboration and verification
Simulated AI suggestion: “Fill all missing values with zero; equal means prove equal service quality.”
This is a prewritten teaching candidate, not live model output. Judge independently, then check each claim; you may use your own candidate instead.
Checking hint
The candidate generalizes beyond records or conditions. Preserve denominators, assistance or scope from the lesson. Softer wording alone is not verification.
