									     Overview of Emerging IT2

• Focus on dissertation-related data
  – How obtained, analyzed, reported
• Many of following slides come from
  – Practical Research by Leedy and Ormrod
• Form of data depends on the type of
  dissertation study

   Primary and Secondary Data

• Data are not “Absolute Truth”
• Primary data
  – Data closest to “Absolute Truth”
  – The most valid and illuminating data
• Secondary data
  – Derived from primary data
  – The form of data usually used by the researcher
    in attempting to discover the truth
   Primary and Secondary Data
       Fingerprint Example
• “Absolute Truth” = true identity of person
• Primary data
  – Fingerprint image, possibly only partial or distorted
• Secondary data
  – Features (minutiae points) taken from the image
  – The form of data usually used by the researcher to
    discover the truth, in this case the person’s identity
Data Type Depends on Research Area
