List of modes (most common values) of discrete or nominal data.ĭivide data into intervals with equal probability. Single mode (most common value) of discrete or nominal data. Median, or 50th percentile, of grouped data. These functions calculate an average or typical value from a populationįast, floating point arithmetic mean, with optional weighting. > from statistics import median > from math import isnan > from itertools import filterfalse > data = > sorted ( data ) # This has surprising behavior > median ( data ) # This result is unexpected 16.35 > sum ( map ( isnan, data )) # Number of missing values 2 > clean = list ( filterfalse ( isnan, data )) # Strip NaN values > clean > sorted ( clean ) # Sorting now works as expected > median ( clean ) # This result is now well defined 18.75 Averages and measures of central location ¶ The NaN values should be stripped before calling these Median_high(), median_grouped(), mode(), multimode(), and The functions affected are median(), median_low(), Undefined behaviors in the statistics functions that sort data or that count Since NaNs have unusual comparison semantics, they cause surprising or

Some datasets use NaN (not a number) values to represent missing data. You may be able to use map() to ensure a consistent result, for If your input data consists of mixed types, Collections with a mix of types are also undefinedĪnd implementation-dependent.
