interpret_icc function

Interpret Intraclass Correlation Coefficient (ICC)

The value of an ICC lies between 0 to 1, with 0 indicating no reliability among raters and 1 indicating perfect reliability.

interpret_icc(icc, rules = "koo2016", ...)

Arguments

• icc: Value or vector of Intraclass Correlation Coefficient (ICC) values.
• rules: Can be "koo2016" (default) or custom set of rules().
• ...: Not used for now.

Rules

• Koo (2016) ("koo2016"; default)

  • ICC \< 0.50 - Poor reliability
  • 0.5 \<= ICC \< 0.75 - Moderate reliability
  • 0.75 \<= ICC \< 0.9 - Good reliability
  • **ICC \>= 0.9 ** - Excellent reliability

Examples

interpret_icc(0.6)
interpret_icc(c(0.4, 0.8))
