Statistical Foundation for Data Science (SFDS)

SFDS module’s objective is to elaborate the various Statistical Techniques from the very basics and how each technique is employed on a real-world data set to analyze and conclude insights. Statistics and its methods are the backend of Data Science to “understand, analyze and predict actual phenomena”. Machine learning employs different techniques and theories drawn from statistical & probabilistic fields.

Prerequisites                          :  some MFDS & DSBD

Objectives/Content               :

  1. Use of statistical software (Python) to summarize data numerically and visually, and to perform data analysis.
  2. Have a conceptual understanding of the unified nature of statistical inference.
  3. Apply estimation and testing methods (confidence intervals and hypothesis tests) to analyze single variables and the relationship between two variables in order to understand natural phenomena and make data-based decisions.
  4. Model and investigate relationships between two or more variables within a regression framework.
  5. Interpret results correctly, effectively, and in context without relying on statistical jargon.
  6. Critique data-based claims and evaluate data-based decisions.
  7. Understand some key differences when applying basic statistics in large data.
  8. Complete a research project that employs simple statistical inference and modeling techniques.
