Twenty-two percent of students selected a variable with high kurtosis (Height).
In the following example, while the student could perceive the symmetry from the
graphical representation of data, this graph was however unproductive as regards the
interpretation of the standard kurtosis coefficient (4.46) that was computed by the
student. The student did not compute the median and mode. We assume he visually
perceived the curve symmetry and from this property he assumed the equality of
mean, median, and mode.
