    • ** NEED TO CALCULATE A CORRELATION COEFFICIENT THAT EXPRESSES THE DEGREE TO WHICH THE TWO MEASURES ARE SIMILAR **
  2. Types of measurement reliability
    • 1. Inter-rater reliability
    • 2. Test-retest reliability
    • 3. Parallel forms
    • 4. Internal Consistency (Cronbach's Alpha)
  3. Inter-rater reliability
    is the extent to which two or more individuals evaluating the same product or performance give identical judgments
  4. Test-retest reliability
    is the extent to which a single instrument yields the same results for the same people on two different occasions
  5. Parallel forms
    is the extent to which two different versions of the same instrument (form A and form B) yield similar results
  6. Internal Consistency (Cronbach's Alpha)
