ABSTRACT
In a completely randomized design, the experimental material should be homogeneous. Usually, the experimental materials are not so homogeneous in nature, particularly in agricultural ?eld experiments. In such a situation, the principle of local control is adopted and the experimental material is grouped into homogeneous subgroups. In this paper, cow milk data are used and applied four different types of treatments. The yield of a cow is analyzed and interpreted using Randomized Complete Block Design (RCBD). Results are explored, tabulated and interpreted
ABSTRACT
Objective To evaluate Test-retest reliability of Mandarin monosyllable lists with equivalency in audibility in hearing loss group. Methods Mandarin monosyllable lists were used to test 18 adults with moderate-to-severe sensorineural hearing loss. Each people was tested twice with an interval of several days and with same test conditions including same lists order, same presentation level, and same tester. List number to begin with was different between people. All test lists for one patient were presented by 30 dB above his hearing threshold levels. Recognition scores were recorded in both tests. The results were analyzed using SPSS. Results Pearson product-moment correlation between the scores of two tests was 0. 931 (P<0. 001). The average critical difference was 16.3 % at the 95 % confidence level after the scores transformed into "rationalized" arcsine unit (RAU). Conclusion The average critical difference is 16. 3% at the 95% confidence level which is less than in the normal hearing group. All the lists have good test-retest reliability, and can be used in extensive clinical practice.
