Final answer:
For phase 1 & 2 of CRISP-DM, which are Business Understanding and Data Understanding, the task is to define the objectives clearly and to familiarize oneself with the data through collection and exploration, rather than actual data mining.
Step-by-step explanation:
The business and data understanding phases of CIRSP-DM (Cross Industry Standard Process for Data Mining) involve the preliminary steps where the data mining task is defined. During the business understanding phase, the main objective is to comprehend the project objectives and requirements from a business perspective, then translate this knowledge into a data mining problem definition. The data understanding phase is centered on collecting initial data, describing the data, exploring the data, and verifying its quality to form a solid basis for extracting insights. During these phases, the task doesn't involve the actual mining of data but rather preparing for it by establishing a clear understanding of the business goals and the data available.
