## Learning Outcomes
- Define core data science concepts, workflows, roles, and commonly used tools.
- Identify data types, sources, and storage methods used in data-driven organizations.
- Evaluate real-world applications of data science across industries and use cases.
- Assess the purpose of data pipelines, exploration, and visualization in data workflows.
- Recognize how modeling techniques like A/B testing and machine learning inform decisions.
## Traditional Course Outline
1. Introduction to Data Science - We'll start the course by defining what data science is. We'll cover the data science workflow and how data science is applied to real-world problems. We'll finish the chapter by learning about different roles within the data science field.
2. Data Collection and Storage - Now that we understand the data science workflow, we'll dive deeper into the first step: data collection and storage. We'll learn about the different data sources you can draw from, what that data looks like, how to store the data once it's collected, and how a data pipeline can automate the process.
3. Preparation, Exploration, and Visualization - Data preparation is fundamental: data scientists spend 80% of their time cleaning and manipulating data, and only 20% of their time actually analyzing it. This chapter will show you how to diagnose problems in your data, deal with missing values and outliers. You will then learn about visualization, another essential tool to both explore your data and convey your findings.
4. Experimentation and Prediction - In this final chapter, we'll discuss experimentation and prediction! Beginning with experiments, we'll cover A/B testing, and move on to time series forecasting where we'll learn about predicting future events. Finally, we'll end with machine learning, looking at supervised learning, and clustering.
