Python - Python Machine Learning - Mean Median Mode Part 3: Understanding Mode in Machine Learning

The mode is the most frequently occurring value in a dataset. It is useful in cases where some values appear more frequently than others, such as in categorical data.

Example 1: Finding Mode in a Dataset

from scipy import stats

data = [1, 2, 2, 3, 4, 4, 4, 5]

mode_value = stats.mode(data)

print("Mode:", mode_value.mode[0])

Explanation: The most common number is 4, so mode = 4.

Example 2: Multiple Modes

data = [7, 7, 8, 8, 9]

mode_value = stats.mode(data)

print("Mode:", mode_value.mode[0])

Explanation: Both 7 and 8 appear twice, so we have multiple modes.
