  • Import both structured and unstructured data into Python
  • Parse unstructured data into structured formats
  • Understand the differences between NumPy arrays and pandas dataframes
  • Overview of where Python fits in the Python/Hadoop/Spark ecosystem
  • Simulate data through random number generation
  • Understand mechanisms for missing data and analytic implications
  • Explore and Clean Data
  • Create compelling graphics to reveal analytic results
  • Reshape and merge data to prepare for advanced analytics
  • Find test for group differences using inferential statistics
  • Implement linear regression from a frequentist perspective
  • Understand non-linear terms, confounding, and interaction in linear regression
  • Extend to logistic regression to model binary outcomes
  • Understand the difference between machine learning and frequentist approaches to statistics
  • Implement classification and regression models using machine learning
  • Score new datasets, evaluate model fit, and quantify variable importance
