consistency coefficient
1.Standard curve was used in the analyzing the change of the consistency of C2H4. The coefficient of recoverywas 95.1%, Linear correlation coefficient of the standard curve 0.9994, standard deviation 0.6% and aberrance coefficient 2.2%. The method was utilizable in analyzing ethylene consistency change in the process reaction of photo -catalyst of titaniumdioxide. It was accurate and useful.
2.Result: The Barthel index scale showed high inter-rater reliability (ICC: 0.987 and 0.945,respectively) and internal consistency at admission and discharge (Cronbach’s alpha coefficient: 0.908 and 0.890,respectively),The Cronbach’s alpha of 10 items in Barthel index is between 0.871 and 0.915. Conclusion: The Barthel index has been shown good inter-rater reliability and internal reliability in patients after acute stroke.
3.Furthermore, the author pointed out some defficiencies of the Kendall coefficient of concordance (W coefficient) and suggest that phi coefficient is a more effective index as rater consistency reliability.
4.Based on the formal measurement table applying the 2(superscript nd) pre-test on 351 students and conducting the examination of the credibility and validity to construct the credibility and validity of the measurement table, the coefficient of inner consistency of individual element in this table was .673~.892, and the coefficient of re-test after the interval of two weeks was .697~.930, with the performance of physical education learning to prove the discriminate validity and criterion-related validity, and with the element analysis to examine the construction validity, the sum of variable amount which could be interpreted was 59.06%, the outcome showed this table was having good credibility and validity that could provide physical education teachers to realize the learning strategies of university students.
