The authors demonstrated that the most common statistical significance test used with r(WG)-type interrater agreement indexes in applied psychology, based on the chi-square distribution, is flawed and inaccurate. The chi-square test is shown to be extremely conservative even for modest, standard ...

✅ effect size + significance ✅ careful handling of NAs If there are NAs present in the selected variables, the legend will display minimum, median, and maximum number of pairs used for correlation tests. There is also a grouped_ variant of this function that makes it easy to repeat the...
get_pvalue_position(): autocompute p-value positions for plotting significance using ggplot2. Facilitating ANOVA computation in R factorial_design(): build factorial design for easily computing ANOVA using thecar::Anova()function. This might be very useful for repeated measures ANOVA, which is har...
(1), in a principled manner. What remains are theoretical and technical issues relating to the tractability, efficiency and feasibility of the inference, but no longer its interpretability. The uncertainty of the estimates and statistical significance of the ensuing analysis follow inherently as a ...
Under the statistical significance premise, the larger the standardized regression coefficient Beta shows the corresponding independent variable has a greater prevalence effect. In this case, under the premise of meeting statistical significance, the order of the magnitude of the effect on prevalence is ...
This paper describes the development and validation of the Reasoning about P-values and Statistical Significance (RPASS) scale. The RPASS was designed to support future research on students' conceptual understanding and misunderstanding ... SJ Lane-Getaz - 《Assessing Student Leaning in Statistics Ia...
The exact p value for significance can be obtained by the generalized Fisher's method with small sample size and a cross-correlation coefficient for the strength of cross-correlation can be obtained based on the R-square analogue for nominal data. For large sample size, chi 2 test can be ...
