DA0-002 · Question #102

A data analyst must combine service calls into low-, medium-, and high-priority levels in order to analyze organizational responses. Which of the following techniques should the analyst use for this t

The correct answer is D. Binning. To categorize continuous or ordinal data into discrete groups, such as low, medium, and high-priority levels, a data analyst should use the binning technique.

Why each option

To categorize continuous or ordinal data into discrete groups, such as low, medium, and high-priority levels, a data analyst should use the binning technique.

AAugmentation

Augmentation involves adding new data or transforming existing data to increase its size or diversity, not categorizing it into groups.

BImputation

Imputation is the process of replacing missing data with substituted values, not for grouping existing data into categories.

CScaling

Scaling is the process of transforming data to fit within a specific range or distribution, often used in machine learning, but not for creating categorical priority levels.

DBinningCorrect

Binning, also known as discretization, is the process of grouping continuous or numerical data into a smaller number of 'bins' or categories. In this scenario, combining service calls into low-, medium-, and high-priority levels effectively creates distinct bins for analysis.
