Q

What are the 8 threats to INTERNAL validity?

A

HITT MMRS

  1. History - variable influenced by time
  2. Instrumentation - variables are measured using different instruments
  3. Testing - subjects remember and respond differently on the post test
  4. Temporal ambiguity - IV may not precede DV
  5. Maturation - subjects mature and therefore change
  6. Mortality - subjects die
  7. Reactivity - observation influences DV (Hawthorne effect)
  8. Selection Bias - change in DV r/t difference in participants NOT intervention
