Get QuantaFor roughly symmetric distributions, report the mean and standard deviation. For skewed distributions or data with outliers, the median and interquartile range describe the typical case better. Reporting both families costs one line and gives readers the full picture.
Skewness near 0 indicates symmetry; positive values mean a long right tail, negative a long left tail. Kurtosis here is excess kurtosis (normal = 0); positive values indicate heavier tails than normal. As a rough screen, absolute skewness below 1 rarely threatens standard analyses; values beyond 2 deserve attention.
The standard deviation uses the sample formula (n - 1). Quartiles use linear interpolation (the R default, type 7); other software may differ slightly for small samples. Skewness and kurtosis use the adjusted sample formulas that SPSS and Excel report.
