#1
What does Interobserver Agreement (IOA) measure?
The consistency between different observers' measurements
ExplanationIOA measures consistency among observers' measurements.
#2
Which statistic is commonly used to calculate Interobserver Agreement (IOA)?
Cohen's kappa
ExplanationCohen's kappa is commonly used for IOA calculations.
#3
What is the purpose of conducting Interobserver Agreement (IOA) calculations?
To determine the reliability of observations made by multiple observers
ExplanationIOA calculations determine the reliability of multiple observers' observations.
#4
What does a Cohen's kappa coefficient of 1 indicate?
Perfect agreement
ExplanationCohen's kappa of 1 indicates perfect agreement.
#5
When is Interobserver Agreement (IOA) typically assessed?
During data collection
ExplanationIOA is typically assessed during data collection.
#6
What is the formula to calculate Percentage Agreement for Interobserver Agreement (IOA)?
Number of agreements divided by total observations
ExplanationPercentage Agreement = (Agreements / Total Observations).
#7
In Interobserver Agreement (IOA), what does a percentage agreement of 100% indicate?
Perfect agreement
ExplanationA 100% percentage agreement indicates perfect agreement.
#8
Which of the following is NOT a factor that affects Interobserver Agreement (IOA)?

ExplanationSample size does not affect IOA.
#9
Which of the following is NOT a method to calculate Interobserver Agreement (IOA)?
Pearson correlation coefficient
ExplanationPearson correlation coefficient is not used for IOA calculations.
#10
Which of the following is true regarding Fleiss' kappa?
It adjusts for chance agreement
ExplanationFleiss' kappa adjusts for chance agreement.
#11
What is the range of Cohen's kappa coefficient?
-1 to 1
ExplanationCohen's kappa coefficient ranges from -1 to 1.
#12
Which of the following is NOT a limitation of Cohen's kappa coefficient?
Inability to handle more than two observers
ExplanationCohen's kappa can handle more than two observers.
#13
When interpreting Cohen's kappa coefficient, what range of values indicates moderate agreement?
0.4 - 0.6
ExplanationCohen's kappa 0.4 - 0.6 indicates moderate agreement.
