Range of response codes, percent agreement, and Cohen's Kappa or intraclass correlation for the constructed-response items used in scaling, grade 8 arts (music) assessment, by item and block: 2008
Block Item Range of response codes Sample size Percent agreement Cohen’s Kappa Intraclass correlation
— Not available. The intraclass correlation is not reported for dichotomously scored items; Cohen's Kappa is not reported for polytomously scored items.
NOTE: Cohen's Kappa is a measure of reliability that is appropriate for items that are dichotomously scored. The intraclass correlation coefficient is most appropriate for items with more than two categories. Item statistics in this table are described on the page Blocks of Items.
