MANAGEMENT OF SUBJECTIVE EVALUATIONS REPRESENTED BY ORDINAL SCALES

• Abstract:

  Common statistical methods, like arithmetic average, are, in principle, not adequate for ordinal scale evaluations, but in practice are frequently used. Specific methods are necessary, more complicated and with limits due to coarse resolution. This paper indicates some ways for overcoming resolution problems, allowing to compare specific and common analysis results. Thereafter it was possible to consider chi-square and skewness as indicators of the possibility of safely using common methods on datasets produced by non-linear metrics.
