• What is the purpose of frequency tables and diagrams?

  They record the number of times something happens.
• Why is recording the frequency of disease important?

  It allows scientists to look at correlations.
• What can be investigated after looking at correlations in disease frequency?

  Possible causes of the disease can then be investigated.
• How can the frequency of disease be measured?

  By counting the number of people affected, the ratio or proportion of those affected, the rate at which new cases occur, and the risk over time.
• What does the risk of disease represent?

• What other factors need to be considered when studying COPD?

  Rates of smoking and genetic factors also need to be considered.
• What does a correlation not always imply?

  A correlation does not always imply cause.
• What is the significance of frequency diagrams in disease studies?

  • Essential in establishing links
  • Help identify possible causes of disease
  • Aid in visualizing data trends
• What do published studies help to do regarding diseases?

  They help to shed light on some conditions and produce questions for further research.
• What is the purpose of using scatter diagrams in disease research?
