What is the 2nd step of CRISP-DM methodology?

The second step of CRISP-DM methodology is to collect the data for processing a solution for the business problem that is defined in the 1st stage.

In order to provide an optimized solution, the data needs to be churned using quantifiable techniques. The relevant data for the business problem can be stored in software (Databases)

It may be collected directly from the sources by conducting surveys or experiments.

What does Primary Data sources mean?

The data collected directly from the sources is analyzed for appropriate solutions. Primary Data can be obtained by conducting experiments to simulate the conditions, collect data by surveys, conduct interviews, focus groups, web pages, or social media or IoT devices data.

What are the Secondary Data sources?

The data generated by various applications, agents, or sources for business are collected and stored using secured software solutions called databases.

The data which is readily available for Data Mining provides quick access to the data and is inexpensive. Though it also has a disadvantage in terms of having a lot of irrelevant data.

What is Data Collection?

Data collection is the systematic process of gathering, measuring, and organizing data from various sources to provide insights and support decision-making.

This data can come from a wide range of sources, such as surveys, customer feedback, online interactions, observational studies, sensors, and automated web scraping. Each of these methods requires specific tools and techniques to ensure data accuracy, consistency, and relevance.

In a data collection interview, candidates may be tested on their understanding of these techniques and their practical applications. Common interview questions for data collection roles may include:

• Describe the steps you would take to ensure data accuracy when collecting information from multiple sources.
• How do you choose between qualitative and quantitative data collection methods for a project?
• Explain a project where you were responsible for data collection. What challenges did you face, and how did you overcome them?
• What are some common tools used in data collection, and how do they differ?

These questions assess a candidate’s theoretical knowledge and ability to implement data collection strategies in real-world situations.

Effective data collection is critical as it impacts the reliability of data insights, which, in turn, can shape the decisions and outcomes for an organization.
