Mode Imputation Method

What is Mode Imputation?

Mode Imputation replaces missing values with the mode (most frequent value) of the non-missing values.

When to Use

• Categorical Data: Best for non-numeric variables
• Discrete Variables: When values are distinct categories
• Simple Baseline: Quick imputation method

Limitations

• May over-represent the most common category
• Doesn't account for relationships between variables
