How to select a Sample?

How to design an Experiment?

  1. We need to select a group of volunteers or subjects(we need to select a sample representative of the entire population).
  2. We will measure their cholesterol level today.
  3. We ask them/ensure that they consume 5–7 walnuts every day for 3 months(let’s assume that all of them co-operates and do this for the next 3 months).
  4. We measure their cholesterol levels after 3 months.
