The hypothesis was examined that the negative
skew found in most distributions of performance ratings
is a function of the verbal labels used as anchors.
When verbal labels quantified on the basis of the
range of real-life performance were employed, distributional
parameters (means, skewness) were affected.
Typically used sets of labels were shown to be more
negative than believed, thus tending to force responses
toward the high end of the scale and thereby contributing
to negative skew.
