How we work this out
What it does
Pick a station, year, month and variable, enter a reading: see where it ranks.
Pearson's Edexcel AS and A-level Mathematics large data set: Camborne, Heathrow, Hurn, Leeming, Leuchars, Beijing, Jacksonville and Perth, 1 May to 31 October 1987 and 2015.
Method
- We take the days for the station, year, month and variable you pick, leaving out n/a days.
- Percentile rank = (days below your reading + half the days equal to it) ÷ days counted × 100.
- A trace of rain (tr) is under 0.05 mm: it ranks above 0 and below any reading of 0.05 mm or more.
