Abstract

ABSTRACT

The table of critical values for significance tests for the R-index was updated and extended in the present article. A more accurate estimator of variance of the R-index, instead of the maximum variance of the R-index, was used in the calculations of the critical values of the table. Sample sizes were extended from 100 to 1,000.

PRACTICAL APPLICATIONS

Prior to this article, the significance of the R-index values could only be determined for sample sizes of 100 and less. This article enables significance to be determined for sample sizes as large as 1,000, which will be especially useful for the larger samples required for consumer testing.
