The Confidence / Significance Level Implies a Certain Cost Ratio Between Type I Error and Type II Error. An Appeal for a Stronger Focus on Decision Theory in Psychological AssessmentAbstract: Psychological assessment requires ...
Most questions across science call for quantitative answers, ideally, a single best estimate plus information about the precision of that estimate. A confidence interval (CI) expresses both efficiently. Early experimental psychologists sought quantitative ...
Null-hypothesis significance testing (NHST) is the primary means by which data are analyzed and conclusions made, particularly in the social sciences, but in other sciences as well (notably ecology and economics). Despite this supremacy however, numerous ...
Abstract. Confidence intervals for the intraclass correlation coefficient (ICC) have been proposed under the assumption of multivariate normality. We propose confidence intervals which do not require distributional assumptions. We performed a simulation ...
Although confidence intervals for means are excellent vehicles for making inferences about population values, they are not always efficient and practical for making inferences about the differences among the means. This article reviews and elaborates on ...
