Case Files: Misrepresentation
Auditing Department of Graphs — Youth Division
Your mission
Graphs submitted to the City Data Archives need investigation. Match each original graph to its data story, identify misleading presentation and use evidence to justify a separate corrected graph.
Protect the evidence. Do not write on, edit or repair the original graphs or stories. Keep drafts, calculations and proposed corrections separate. Do not assume an inconsistency is an accidental error in the website.
The supplied original assignment contains five cases. Follow your teacher’s assigned selection, team roles and submission instructions in Google Classroom.
From evidence to audit
- Team analysis: read every story and match the graphs using labels, shapes, scales and data patterns.
- Paper draft: discuss possible violations and record evidence on separate paper. Each auditor takes responsibility for an assigned graph.
- Reconstruct separately: use the established source data to create a clear graph with an appropriate type, title, labels, units, scale and legend where needed.
- Explain and submit: finalise your Correction Ticket and corrected graph. Submit using the assigned Google Classroom instructions. The website does not submit work for you.
Original case stories
Read the stories in the source PDF before deciding which graph belongs to each case.
The evidence gallery
These are full-page renders of the original graph pages. Match them to the stories yourself; no solution is revealed here. Open the PDF for the original, zoomable evidence.
Some original graphs are images with limited text accessibility. Use the matching source story and a teacher or partner to describe visual features when needed; the investigation intentionally leaves interpretation to the auditor.
Your Correction Ticket
Draft here after completing the assigned paper analysis. Text is saved only in this browser when storage is available. Download your ticket before switching devices or clearing browser data. No name or account is required.
Your corrected graph is a separate submission item. Use the graphing tools assigned by your teacher, or open Graph Lab for a single-series bar, line or circle graph.
