Which statement about the data science methodology is correct?

The correct statement highlights that the data science methodology is essential for establishing a clear context before diving into the analytical process. Starting with Business Understanding is fundamental because it ensures that the problems being addressed are aligned with the business goals and requirements. This phase involves identifying and defining the objectives, understanding stakeholder needs, and determining the overall scope of the project. By beginning with Business Understanding, data scientists can effectively tailor their analysis to provide actionable insights that are relevant to the organization's strategy.

The correct approach maintains that the methodology is iterative and flexible, allowing for the different stages to be revisited as new insights are gained. Although all stages of data science are important, the initial focus on business goals sets a foundation for the entire process. This is crucial because without a clear understanding of the business context, subsequent stages, such as data preparation and modeling, may lead to results that don't effectively address the core issues at hand.

In contrast, claims regarding dependence on specific technologies or tools may misinterpret the essence of data science methodology, which is more about the process and framework rather than the tools used. Similarly, the suggestion that it requires going through all stages successively before repeating them does not reflect the actual iterative nature of data science, where revisiting earlier stages is common based
