12 values - mean 7, SD 4.3901 (sample).

  • The mean (7) is above the median (6.5), hinting at right skew - a few large values are pulling the average up.
  • Coefficient of variation is 62.7%, indicating high relative spread - the data is widely dispersed relative to the mean.
  • Distribution shape: approximately symmetric.
  • Tail weight: lighter tails than normal (platykurtic, kurtosis -1.2).

Next stepIf outliers are present, consider whether they are data errors or genuine extreme values before reporting the mean. The median is more robust to outliers than the mean.
