Learn, practise, explain

Try the exercise before reading its explanation. Answer the self-check questions in your own words, then compare your reasoning with the answers. Revisit any difficult section before moving on. No account or payment is needed.

  1. 01

    How to check an online claim: sources, dates and evidence

    A forwarded notice, a cropped screenshot or a striking headline can travel further than its evidence. Learn a repeatable way to investigate before acting or sharing.

    Learning outcome: Produce a short evidence note that separates the claim, supporting record, missing information and a proportionate next step.

  2. 02

    Percentage change and percentage points: read headlines correctly

    “Up by 50%” sounds simple until the starting number changes. Work through attendance, registrations and prices to compare quantities fairly.

    Learning outcome: Calculate both kinds of change, detect a changing denominator, and rewrite a dramatic headline into a precise numerical statement.

  3. 03

    How to read charts: axes, scales and missing data

    Two pictures can show the same numbers and feel very different. Learn to read the labels, check the scale and explain the pattern without inventing a cause.

    Learning outcome: Explain a bar or line chart, detect a misleading baseline, distinguish missing data from zero and write a careful caption.
