Compute for the percent agreement observed, using all of the cells in the table. 3. Compute for the percent agreement expected by chance without creating a new table. Limit up to 5 decimal places while computing and round-off to the whole number only for your final answer. 4. Compute for the Kappa test ratio. Use the computed value of the percent agreement observed in item 2. 5. Interpret the result of the Kappa test ratio. (Almost perfect, Substantial, Moderate, Fair, Slight, Less than) Cohen 6.
