The correct answer is D. All of the mentioned.
Data science is a field that combines domain expertise, programming skills, and knowledge of mathematics and statistics to extract meaningful insights from data. It is a rapidly growing field with a wide range of applications, including business intelligence, fraud detection, and healthcare.
Statistics is the study of the collection, organization, analysis, interpretation, presentation, and communication of data. It is a fundamental tool for data science, as it provides the foundation for understanding and analyzing data.
Machine learning is a field of computer science that gives computers the ability to learn without being explicitly programmed. It is a powerful tool for data science, as it can be used to automate the analysis of data and identify patterns that would be difficult or impossible to identify manually.
Data visualization is the process of transforming data into a visual representation that helps people understand the data. It is an important tool for data science, as it can be used to communicate insights from data to stakeholders in a clear and concise way.
In conclusion, all of the mentioned are key data science skills. Statistics, machine learning, and data visualization are all essential for extracting meaningful insights from data.
