Understanding Fly's Kappa

What is the primary use of Fly's Kappa?

• To calculate the average score of raters

• To assess agreement between more than two raters

• To determine the accuracy of a single rater

• To measure the validity of a test

Which type of variable is Fly's Kappa used for?

• Ordinal

• Metric

• Nominal

• Interval

In the context of Fly's Kappa, what does interrater reliability refer to?

• The consistency of a single rater over time

• The validity of the measured variable

• The agreement between multiple raters

• The accuracy of a measurement tool

What is a limitation of Fly's Kappa?

• It is only applicable to metric variables

• It requires complex software to calculate

• It cannot be used for more than two raters

• It only measures reliability, not validity

Which software is mentioned for calculating Fly's Kappa?

• Data Tab

• SPSS

• R Studio

• Excel

What is the first step in manually calculating Fly's Kappa?

• Identifying the number of variables

• Counting the number of raters

• Calculating the expected agreement (Pe)

• Determining the observed agreement (Po)

How is the expected agreement (Pe) calculated?

• By averaging the ratings of all raters

• By squaring and summing the proportions of each category

• By dividing the number of agreements by the total number of ratings

• By multiplying the number of raters by the number of categories

What does a Fly's Kappa value of 0.19 indicate?

• No agreement

• Moderate agreement

• High agreement

• Slight agreement

What is the significance of calculating Po in Fly's Kappa?

• It identifies the variable type

• It measures the expected agreement

• It determines the number of raters

• It calculates the observed agreement

What is the final step in calculating Fly's Kappa manually?

• Dividing Po by Pe

• Multiplying Po by Pe

• Inserting Po and Pe into the Kappa formula

• Subtracting Pe from Po
