D5 (median) = 33.0000 across 15 values

  • The median (D5) is 33.0000, meaning half of your 15 values fall below this point and half above.
  • The interdecile range (D9 - D1) is 48.2000, covering the middle 80% of your data (90.9% of the total range).
  • The upper half (D5-D9 = 29.0000) is more spread out than the lower half (D1-D5 = 19.2000), suggesting a right-skewed distribution.

Next stepPair deciles with quartiles (Q1, Q3) and the interquartile range to get a fuller picture of spread and outliers, or use a box-and-whisker plot to visualize the full five-number summary.
