Sampling methods

• Continuous sampling

  • All instances of a target behaviour are recorded.
  • For complex behaviours, however, this method may not be very feasible or effective
• Event sampling

  • Counting the number of times a particular behaviour occurs
  • For example, how many times an individual smiles at a movie
  • Strength: Adds focus/structure to the observation
  • Weakness: May miss relevant behaviour that isn't on the checklist
• Time sampling

  • Recording behaviour within a pre-established time frame
  • For example, making notes on what an individual is doing every 30 seconds
  • Strength: Adds focus/structure to the observation
  • Weakness: Can miss behaviour that occurs outside of recording periods
