What are some common data normalization methods?

Common data normalization methods include Min-Max scaling, Z-score normalization, and Decimal scaling.

Can you explain Min-Max scaling?

Min-Max scaling transforms features to a fixed range, usually [0, 1], by subtracting the minimum and dividing by the range.

What about Z-score normalization?

Z-score normalization standardizes data by subtracting the mean and dividing by the standard deviation, resulting in a distribution with a mean of 0 and a standard deviation of 1.

When should I use each method?

Use Min-Max scaling when you need bounded values, and Z-score normalization when your data follows a Gaussian distribution.
