What is Median Imputation?

Median Imputation replaces missing values with the median (middle value) of the non-missing values for that feature.

Advantages Over Mean

• Robust to Outliers: Not affected by extreme values
• Appropriate for Skewed Data: Better for non-normal distributions

When to Use

• Continuous data with outliers
• Skewed distributions
• When preserving central tendency is important
