That is: interval and ratio variables are metric variables. Because calculations are allowed, we typically analyze them with descriptive statistics such as means; standard deviations; skewnesses. Data Analysis - Next Steps We just argued that categorical variables define groups of cases and we use ...
The internal consistency achieved in this study was a Cronbach’s alpha value of α = 0.92 Data analysis A descriptive analysis of the WHOQOL-BREF items (average score, standard deviation, skewness, kurtosis, item-total correlation, and Mardia’s multivariate normality test) was used to determine...

All OHQ items were normally distributed (i.e., their skewness and kurtosis values were ≤ |1|). Descriptives for each OHQ item are reported in Table 1. Table 1 Descriptive statistics for the items of the Oxford Happiness Questionnaire (OHQ) Full size table Socio-demographic Gender differences...
aSecond, it explains the globalization-skewness puzzle documented in the empirical part of our paper: a multilateral reduction in trade costs leads to a flattening of the size distribution of firms. 其次,它解释在我们的纸的经验主义的部分提供的全球化反称性难题: 多边减少在商业费用导致铺平企业的大...
Normality was assessed via the skewness-kurtosis test, with outliers identified using stem-and-leaf plots. Group comparisons were conducted using one-way ANOVA, with P < 0.05 indicating statistical significance. Discussion The establishment of an RMP provides standardized operational procedures and ...
The rescaled range R(t, s) / S(t, s) is shown by extensive computer simulation to be a very robust statistic for testing the presence of noncyclic long run statistical dependence in records and, in cases where such dependence is present, for estimating its intensity. The processes examined...
If a data set is arranged in order of magnitude then the middle score of that data set is known as the median. A special feature of the median is that it is practically not affected by the skewness of a distribution. Answer and Explanation: We ...
