Statistics, a branch of mathematics widely used in various fields, plays a fundamental role in the collection, organization, analysis, and interpretation of numerical data.
It enables informed decision-making and the extraction of valuable conclusions about populations and phenomena under study.
In order to promote learning and the application of statistics, several educational institutions are offering free courses that provide students with the opportunity to acquire statistical and data analysis skills.
Here are three prominent courses that you can take for free:
Python and Statistics for Financial Analysis
The Hong Kong University of Science and Technology offers an online course that combines Python programming with statistical concepts applied to financial analysis.
In this course, participants will learn how to import, preprocess, visualize, and manipulate financial data using Python’s pandas library.
They will also gain knowledge about essential statistical concepts such as random variables, distributions, confidence intervals, and linear regression. Additionally, they will have the opportunity to build a trading model using linear regression and evaluate its performance.
No prior programming experience is required, and the course provides a Jupyter Notebook environment for practicing without the need to install additional applications.
