The 90th percentile of your 6 values is 32.5.

  • About 90% of your data falls at or below 32.5, with the remaining 10% above it.
  • The result uses linear interpolation: when the percentile lands between two data points, the value is blended proportionally, so it may not equal any number in your original list.
  • Your five-number summary: min 4, Q1 9.75, median 15.5, Q3 21.25, max 42.
