Teach data science with Python with the only interactive introduction that’s fully integrated with Jupyter Notebooks
Data Science Foundations with Python is the first complete, interactive introduction to the foundational algorithms and techniques for Python in data science.
- Students can write and edit live code, create data visualizations, and output images right in the zyBook
- Includes data preprocessing, regression techniques, supervised and unsupervised learning algorithms, decision trees, neural networks, ensemble methods, and model evaluation techniques
- Jupyter Notebooks is embedded in the zyBook, so students work with real-world, professional tools
- Continuously updated with the latest advances in data science
Data science is interactive; it requires coding and live investigations of data sets. To do all that within a digital zyBook is really powerful.”
–Â Co-author Dr. Aimee Schwab-McCoy
Dr. Schwab-McCoy explains the benefits of zyBooks for data science instructors and students:
What is a zyBook?
Data Science Foundations with Python is a web-native, interactive zyBook that helps students visualize concepts to learn faster and more effectively than with a traditional textbook.
Since 2012, over 1,200 universities and colleges across the country have adopted web-native zyBooks to transform their STEM education.
zyBooks benefit students and instructors:
- Instructor benefits
- Customize your course by reorganizing existing content, or adding your own
- Continuous publication model updates your course with the latest content and technologies
- Gain insight into students’ progress, reading and participation with robust reporting
- Save time with auto-graded labs and challenge activities that seamlessly integrate with your LMS gradebook
- Build quizzes and exams with over 300 included test questions
- Student benefits
- Learning questions and other content serve as an interactive form of reading
- Instant feedback on labs and homework
- Concepts come to life through extensive animations embedded into the interactive content
- Save chapters as PDFs to reference the material at any time
- Gain real-life, professional experience working with industry standard Jupyter Notebooks
Embedded Jupyter Notebooks
The Data Science Foundations with Python zyBook is fully integrated with the industry standard Jupyter Notebooks web-based computing platform. So students will gain real-life experience writing and editing live code, creating data visualizations, and experimenting by changing parameters of different models to evaluate their performance with a professional application.
Jupyter Notebooks can also be downloaded for offline use.
In this video, Dr. Schwab-McCoy demonstrates the power of zyBooks’ embedded Jupyter Notebooks:
