Type of Reliabilty

?

1. Which describes Test-related Reliability (TRR)?

  • indicates the degree of agreement among raters –gives score of homogeneity or consensus in ratings by different judges
  • same test given with time delay, if both times correlate = test stability ( not suitable if skills, memory, or motivation can influence)
  • 2 variations of test measuring same construct  correlation = reliability
  • 1 test split into 2 halves, per individual scores are obtained and correlated (need to be adjusted with Spearman-Brown Formula)
