Lesson details

Learning outcome

I can check pet data for mistakes and explain why they are wrong.

Key learning points

  1. Data can sometimes be wrong.
  2. Mistakes make comparisons unfair.
  3. Data can be checked and corrected.

Keywords

  • Accurate - something that is correct and without mistakes

  • Error - something that is wrong

  • Check - look at something carefully to see if it is correct

Common misconception

Once data is written, it cannot be changed.

Data can be checked and corrected if there are mistakes.

Teacher tip

A key point in this lesson is that data can contain mistakes. Encourage pupils to check carefully and explain why something may not be accurate, rather than just spotting errors.
