Misclassification

  • Bryan Kestenbaum
Chapter

Learning Objectives

  1. 1.

    Misclassification arises from errors in measuring study data.

     
  2. 2.

    Nondifferential misclassification results from random errors that occur roughly equally within a study population.

     
  3. 3.

    Nondifferential misclassification usually yields measures of association that are closer to the null value of 1.0.

     
  4. 4.

    Differential misclassification results from systematic errors that occur preferentially within a subset of a study population.

     
  5. 5.

    Differential misclassification may obscure true associations, falsely amplify associations, or create false associations

     
  6. 6.

    Uniform data collection procedures help to minimize the possibility for differential misclassification.
