Compute the test statistic as {eq}\chi^{2}=c_{1}+ c_{2}+..+c_{k} {/eq} and degrees of freedom {eq}df=k-1 {/eq}, or the number of categories - 1. Compute the p-value for the Chi-Square distribution with {eq}df {/eq} degrees of freedom...
To measure the extent of agreement between the 2 independent coders, the κ statistic was used and calculated according to the methods by Landis and Koch.17 The frequency of discrepancies between the coders was computed using the Kappa Calculator (Statistics Solutions),18 and the κ statistics wer...
Using a Chi-square distribution table with DF=1 and χ2=0.116884, our test statistic falls between the values of 0.00016 and 1.642, which have p-values of 0.975 and 0.2, respectively. Our p-value must lie between these values. Using an online p-value calcul...
