6. Other students misinterpreted the skewness coefficient or assumed that the
equality of mean, median and mode was enough to show the symmetry of
the distribution, accepted as normal a distribution with no horizontal
asymptote, made a rough approximation when formally or informally
checking the rule (μ– kσ, μ+ kσ), accepted too many outliers in a normal
distribution, or misinterpreted the values of kurtosis.
