What is the primary purpose of using the Intraclass Correlation Coefficient (ICC)?
What is the primary purpose of using the Intraclass Correlation Coefficient (ICC)?
- To calculate the minimum clinically important difference (MCID) of a measurement
- To measure the level of agreement between two raters
- To provide unstandardized estimates of measurement reliability in units of measure
- To standardize estimates of measurement reliability without units (correct)
Which of the following is the recommended interpretation for an ICC value greater than 0.75?
Which of the following is the recommended interpretation for an ICC value greater than 0.75?
- Good reliability (correct)
- Indicates the need to choose the Kappa statistic instead
- Poor to moderate reliability
- Best for clinical measurements
What is the key difference between the ICC and the Standard Error of Measurement (SEM)?
What is the key difference between the ICC and the Standard Error of Measurement (SEM)?
- The ICC is more appropriate for clinical measurements, while the SEM is better for research purposes
- The ICC is used to measure agreement between raters, while the SEM measures reliability
- The ICC provides standardized estimates of reliability, while the SEM provides unstandardized estimates (correct)
- The ICC is used for ordinal data, while the SEM is used for interval or ratio data
