🌟 Udacity Data Analyst Nanodegree

Focus area: Data analysis using Python.

Period: Aug - Oct 2021 (estimated completion)

At the end of the course, these are my 🔑 key learnings:

  • Learn the data analysis process of wrangling, exploring, analyzing, and communicating data, and work with data in Python, using libraries like NumPy and Pandas.
  • Apply inferential statistics and probability to real-world scenarios, such as analyzing A/B tests and building supervised learning models.
  • Learn the data wrangling process of gathering, assessing, and cleaning data and use Python to wrangle data programmatically and prepare it for analysis.
  • Apply visualization principles to the data analysis process and explore data visually at multiple levels to find insights and create a compelling story.
