python calculate mean by hand code example

Example 1: calculate mode in python

# Calculating the mode when the list of numbers may have multiple modes
from collections import Counter

def calculate_mode(n):
    c = Counter(n)
    num_freq = c.most_common()
    max_count = num_freq[0][1]
    
    modes = []
    for num in num_freq:
        if num[1] == max_count:
            modes.append(num[0])
    return modes

# Finding the Mode

def calculate_mode(n):
    c = Counter(n)
    mode = c.most_common(1)
    return mode[0][0]

Example 2: finding median on python

def calculate_median(n):
    N = len(n)
    n.sort()
    
    #find the median
    if N % 2 == 0:
        #if N is even
        m1 = N / 2
        m2 = (N / 2) + 1
        #Convert to integer, match post
        m1 = int(m1) - 1
        m2 = int(m2) - 1
        median = (n[m1] + n[m2]) / 2 
    else:
        m = (N + 1) / 2
        # Convert to integer, match position
        m = int(m) - 1
        median = n[m]
    
    return median
