Course Summary
The Introduction to Data Science class will survey the foundational topics in data science, namely:
 Data Manipulation
 Data Analysis with Statistics and Machine Learning
 Data Communication with Information Visualization
 Data at Scale  Working with Big Data
The class will focus on breadth and present the topics briefly instead of focusing on a single topic in depth. This will give you the opportunity to sample and apply the basic techniques of data science.
This course is also a part of our Data Analyst Nanodegree.
