Lesson details

Key learning points

  1. Different methods are used to test products.
  2. Qualitative and quantitative data is gathered when testing products.
  3. Qualitative and quantitative data is analysed to influence designs.

Keywords

  • Non-destructive - testing without destroying the material or product

  • Qualitative - data recorded using words

  • Quantitative - data recorded using numbers

  • Variables - something that can change and affect test results

  • Control measures - keeps conditions consistent to ensure a fair test and accurate results

Common misconception

Data always involves numbers.

Data is information and can be recorded using both numbers and words.

Prepare for the test with relevant resources. The lesson uses citrus fruit juicers, but you could substitute with other available kitchen equipment. If using citrus fruit juicers, you will also need chopping board knives, citrus fruit, measuring jugs and juicers.
