DA0-001 · Question #112

When analyzing the values of two variables, you decide to convert both variables so they are on a scale of 0 to 1. What term describes this action?

The correct answer is B. Normalization. Converting variable values to a common scale of 0 to 1 is called Normalization (specifically, Min-Max Normalization). The formula is: (value − min) / (max − min). This technique ensures that no single variable dominates an analysis due to differences in scale. Filtering removes…

Explanation

Converting variable values to a common scale of 0 to 1 is called Normalization (specifically, Min-Max Normalization). The formula is: (value − min) / (max − min). This technique ensures that no single variable dominates an analysis due to differences in scale. Filtering removes rows/columns based on criteria. Transposition swaps rows and columns. Aggregation summarizes data (e.g., SUM, AVG). Only normalization describes the 0-to-1 rescaling action.
