I love statistics and always look for ways to incorporate them in my every day work but. However, the proportion successfully typed (sampling rate) is, of course, known. I mean they'll tell you whether one is statistically . A Hypothesis Test for two Independent Proportions answers a research question through statistical analysis about two independent proportions. 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. Throughout this discussion the words 'sample' and 'population' will have these specific meanings. This hypothesis test looks at whether or not there is a significant Hence the probability of both variables success rate is the same. 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. To use statistical nomenclature, the cases that are successfully typed thus constitute our 'sample' from the 'population' of the sputum confirmed TB subjects.
