It further presents a comparison and evaluation of the two statistical concepts. It mentions that the p-value...

    Ecologists often contrast diversity (species richness and abundances) using tests for comparing means or indices. However, many popular software applications do not support performing standard inferential statistics for estimates of species richness and/or density. In this study we simulated the...

    Confidence intervals within hypnosis would improve research, especially confidence intervals for effect sizes. Moreover, within hypnosis research, confidence intervals are needed for reliability and validity measures. This paper describes definitions and issues related to confidence intervals....

    Background: Many lower limb disorders are related to calf muscle tightness and reduced dorsiflexion of the ankle. To treat such disorders, stretches of the calf muscles are commonly prescribed to increase available dorsiflexion of the ankle joint. Hypothesis: To determine the effect of static...

    Background: The reporting interval is the incremental value chosen in reporting analyte concentration. Reporting intervals for different analytes are often inappropriately narrow, when analytical imprecision and biological variability are considered. Methods: We have used statistical techniques...
