Another way to illustrate the magnitude of the differences is to indicate the distribution of significant differences, with the average T values represented against the absolute differential values proposed by Bland and Altman (1986, 2003). This graph (see Figure 4) shows that 18 of the 30 differences observed (60%) 1 SD of differences (SD – 5.7). The boundaries of concordance in this study, as defined by Bland and Altman (2003), containing 95% of differences in similar populations, are 12.2 to 10.2 T points, an interval that contains all the differences observed in this study. The graphical approach used to assess the size of differences therefore reflects the result of a 100% failure agreement when CCI is considered reliable in calculating reliable differences.

Since the rankings are only in the order of observations, the relationships between the rankings are always linear, the initial variables are linearly related. Thus, Spearmans Rho not only has the same interpretation as the Pearson correlation, but it also applies to non-linear relationships. Spearman ⌢ is between -1 and 1, with 1 and 1 indicating a perfect positive (negative) correlation; If ⌢ 0, there is no association between the variables ui and vi. If ⌢ `1` then qi ri, in this case, consider a sample of subjects n and a continuous bivariate result, (ui, vi), of each subject in the sample (1≤i≤n). The Pearson correlation is the most popular statistic for measuring the association between the two variables ui and vi: We first assessed the reliability of the intergroup within and beyond the rating subgroups. Reliability between the speeders, expressed by intra-class correlation coefficients (CCIs), measures the degree to which the instrument used is able to distinguish between participants indicated by two or more advisors who reach similar conclusions (Liao et al., 2010; Kottner et al., 2011). Therefore, the reliability of advisors is a criterion of the quality of the assessment instrument and the accuracy of the evaluation procedure, not a measure of the quantification of the agreement between credit rating agencies.
It can be considered as an estimate of the reliability of the instrument in a specific study population. This is the first study to assess the reliability of the ELAN questionnaire between the holds. We talk about the high reliability of Inter-Rater for the father-mother as well as for parent-teacher evaluations and for the study population as a whole. There was no systematic difference between the subgroups of advisors. This indicates that the use of ELAN with maternal assistants does not diminish her ability to distinguish between children with high vocabulary and low vocabulary.
