Choose a learning activity. Practice and Test use short shuffled attempts. Repeat quiz practice to access more of the full question bank.

Unit focus

  • A distribution describes how values are spread and concentrated. Different displays highlight different features, so effectiveness depends on the question, scale, audience and accuracy.
  • Use this routine: Identify question → Read scale/key → Describe concentration/gaps/extremes → Compare variation → Evaluate display → Support with data.
  • Watch for tall-looking difference assumed large: Read the axis scale and actual values.
