This study concluded that slight difference was found between the positivity rate of HR-HPV infection detected by the HC-II and PCR assay in OSMF and OSCC cases and the HC II assay seemed to have better sensitivity in case of OSCC. Thus Proportion: Comparison of Seven Methods (1998, Statistics in Medicine, 17, 857-872). Estimates where z₁-α⁄ 2 is the 1-α⁄2 percentile of the standard normal distribution; α is the Type I error rate and is the complement of the confidence level. Glantz, Primer of Biostatistics, McGraw-Hill, New York, NY, 2002. I love statistics and always look for ways to incorporate them in my every day work but. Level of agreement was calculated by both absolute agreement and Cohen's kappa statistic (k), a measure of the agreement between two methods in excess of that due to chance [22]. It is certainly true that a blind application and reliance on statistical methods without a good understanding of how to interpret the results can be dangerous - but this is not a failing of the methods. However, the proportion successfully typed (sampling rate) is, of course, known. Throughout this discussion the words 'sample' and 'population' will have these specific meanings. Why would one need a statistical test to compare campaign response rates ??? The methods for estimating the proportion of cases due to recent transmission by using cluster analysis are discussed. I mean they'll tell you whether one is statistically . In statistics, sample data is often used to help find estimates of population parameters. To use statistical nomenclature, the cases that are successfully typed thus constitute our 'sample' from the 'population' of the sputum confirmed TB subjects.
