  3. 3. Table 4.1 A Comparison of Primary and Secondary Data
  4. 4. Advantages <ul><li>Time savings </li></ul><ul><li>Relevance </li></ul><ul><li>Availability </li></ul><ul><li>Obtainable in a short period of time </li></ul><ul><li>Low cost </li></ul><ul><li>Accessibility </li></ul><ul><li>Complements primary data </li></ul>
  5. 5.

  6. 6. Is the Secondary Data appropriate for your study? <ul><li>Is the subject matter consistent with your problem definition? </li></ul><ul><li>Do the data apply to the population of interest? </li></ul><ul><li>Do the data apply to the time period of interest? </li></ul><ul><li>Do the data appear in the correct units of measurement? </li></ul><ul><li>Do the data cover the subject of interest in adequate detail? </li></ul>
