Two proportions from the same sample of observations or from matched-pair samples are correlated. A number of studies proposed interval estimation for the difference in correlated proportions (e. Considering that confidence intervals (CI) are more informative than point estimates but the CI for the difference in correlated proportions is not readily(More)

Abstract This paper studies the performance of multihop free-space optical (FSO) systems using the subcar-rier binary phase-shift keying modulation (BPSK) over atmospheric turbulence channels. We propose a(More)
Testing the equality of several independent group means is a common statistical problem in social science. The traditional analysis of variance (ANOVA) is one of the most popular methods. However, the ANOVA F test is sensitive to violation of the homogeneity of variance assumption. Several alternative tests have been developed in response to this problem of(More)
Effect sizes are strongly encouraged to be reported in addition to statistical significance and should be considered in evaluating the results of a study. The choice of an effect size for ANOVA models can be confusing because indices may differ depending on the research design as well as the magnitude of the effect. Olejnik and Algina (2003) proposed the(More)
Measures of effect size are recommended to communicate information on the strength of relationships. Such information supplements the reject/fail-to-reject decision obtained in statistical hypothesis testing. Because sample effect sizes are subject to sampling error, as is any sample statistic, computing confidence intervals for these statistics is a useful(More)
