Study Notes

Data Science Problem-Solving Process

The data science problem-solving process involves multiple steps: problem definition, data collection, data cleaning, data visualization, modeling, and deployment.
These steps are not always linear, and data scientists often iterate between them.

Challenges in Data Science

The most challenging part of the data science problem-solving process is often identifying the problem to solve.

Data Analysis

Data analysis is the process of extracting insights and patterns from data using various techniques, including data mining and statistical modeling.
The main components of data analysis are: problem definition, data collection, data cleaning, data transformation, and model building.

Machine Learning

Machine learning is a type of artificial intelligence that enables computers to learn from data without being explicitly programmed.
Machine learning typically works with structured or semi-structured data.

Characteristics of a Good Data Scientist

A good data scientist should possess a combination of skills, including business acumen, technical skills, and communication skills.
A good data scientist should be able to extract insights from data, communicate findings effectively, and make recommendations that drive business decisions.
