NAEP Analysis and Scaling → Initial Activities → Constructed-Response Interrater Reliability → Range of Response Codes, Percent Agreement, and Cohen's Kappa or Intraclass Correlation for the Constructed-Response Items From Previous Years, Rescored in 2008, Age 17 Mathematics Long-Term Trend Assessment, by Item and Block: 2008
| Block | Item | Range of response codes | Sample size | Percent agreement | Cohen’s Kappa | Intraclass correlation |
|---|---|---|---|---|---|---|
| — Note 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.
