What Is Cohen's Kappa? How Is Agreement or Reliability Between

Question

Examlex · Accepted Answer

The Answer is Cohen's kappa is a statistical measure used to assess the agreement or reliability between two or more coders when coding categorical data. It takes into account the agreement that would be expected by chance and provides a more robust measure of agreement than simple percent agreement.

To determine the agreement or reliability between coders using Cohen's kappa, the following steps are typically followed:
1. Select a sample of data that needs to be coded by multiple coders.
2. Have each coder independently code the same set of data.
3. Calculate the observed agreement between the coders, which is the proportion of times they agreed on the coding.
4. Calculate the expected agreement by chance, which takes into account the distribution of codes and the marginal totals for each category.
5. Use these values to calculate Cohen's kappa coefficient, which ranges from -1 to 1. A value of 1 indicates perfect agreement, 0 indicates agreement equivalent to chance, and negative values indicate agreement worse than chance.

Overall, Cohen's kappa provides a more nuanced understanding of agreement between coders by accounting for chance agreement and is widely used in fields such as psychology, medicine, and social sciences to assess inter-rater reliability.
