Data versus TruthPractical Research by Leedy and Ormrod

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 DataFingerprint 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
