Harmonic Mean in Python
# Dataset runners = [4, 3, 6, 8, 10, 11, 5] Example 1 Manual Calc
n = len(runners) # Calculate the sum of reciprocals reciprocal_sum = sum(1/x for x in runners) # Calculate harmonic mean harmonic_mean_manual = n / reciprocal_sum harmonic_mean_manual 
Example 2 statistics
import statistics as stats # Calculate harmonic mean data = runners harmonic_mean_stats = stats.harmonic_mean(runners) print(harmonic_mean_stats) 
df.loc[idx] df.loc[idx] Example 3 scipy
from scipy.stats import hmean harmonic_mean_scipy = hmean(data) print(harmonic_mean_scipy)
