THE EDITOR'S DESK / INTERACTIVE EXPERIMENT

TRUTH
LENS.

Can the same data tell two completely different stories? Adjust the graphs, investigate missing information, and decide what deserves to be published.

EXPERIMENT 01 / VISUAL PERSUASION

CAN YOU MAKE A SMALL RISE LOOK HUGE?

The school newsletter says visitor numbers have “skyrocketed”. These are the same eight weekly totals as your Attendance tab. Move the controls to see how a graph can change the impression without changing a single number.

CREATIVE HUB ATTENDANCE

Number of visitors each week • fictional data
ZERO BASELINE
Visitors per week

Showing fewer weeks can hide important context.

EXPERIMENT 02 / WHO WAS COUNTED?

84% HAPPY… BUT WHO ANSWERED?

The library says “almost everyone is satisfied”. Open your Student Survey sheet, use SUM to find three totals, then enter them below. The denominator changes what a percentage means.

BRING IN THE SPREADSHEET DATA

Use your own calculated totals, not a guess. The lab will update live.

POSITIVE / THOSE WHO REPLIED—Of respondents
CONFIRMED POSITIVE / ALL INVITED—Of everyone invited
Enter your totals to compare two claims made from the same survey.
EXPERIMENT 03 / TRACE THE RECORDS

EVERY NUMBER HAS A SOURCE.

Investigate the Data Audit tab. Click any entries that deserve checking. You are a fact checker, not a data eraser: an unusual number is a reason to investigate, not proof of a mistake.
