Interpret Intraclass Correlation Coefficient (ICC)

Source: R/interpret_icc.R

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
