Sampling methods

• What is the purpose of increasing reliability in research?

  To ensure consistent and accurate results
• What is the difference between unstructured and structured observations?

  Unstructured has continuous recording; structured uses systematic sampling
• What are the two systematic sampling methods used in structured observations?

  • Event Sampling
  • Time Sampling
• What does event sampling involve?

  Counting occurrences of a specific behavior or event
• When is event sampling best used?

  To determine how often a specified behavior occurs
• What is time sampling in structured observations?

  Recording behavior during a predetermined time period
• When is time sampling best used?

  To estimate individual levels of a behavior
• What is a benefit of using time sampling in observations?

  It helps manage observations without being overwhelmed
• What is a potential weakness of time sampling?

  Behaviors may be missed during intervals
• How does missing behaviors during time sampling affect the study?

  It reduces the overall reliability of the study
• What reliability score is mentioned in the study material?

  A score of 0.7 or above
