Exploratory Data Analysis (EDA) involves multiple techniques that extract meaningful information and valuable insights from the data. The main purpose of EDA is to investigate datasets to reveal the underlying structures and the challenges and opportunities that come with data without attempting to make predictions using machine learning models. EDA is the first attempt in data mining and the first exercise to make further decisions. It is a critical phase in any data analysis or data science project by generating summary statistics in a dataset as well as constructing various graphical representations to help understand the hidden knowledge of data and answer the businesses' questions of why and how.

TechClass Exploratory Data Analysis with Python online course will introduce you to the practical knowledge and the main pillars of EDA, including data exploration, data preparation, visualization, data relationships, and clustering using Python programming language. Apart from the intuitions, you will get familiar with how EDA steps are implemented by various Python libraries such as NumPy, Pandas, Matplotlib, and Scikit-learn. By the end of this course, you will be prepared to enter the fantastic world of data analysis towards amazing job opportunities in the industry.

jam-packed course

I think the course was interesting and complete. It was very good for me that the concepts were explained step by step, and the concepts were taught with simple code snippets.

Love this course

This course was beneficial for me. Previously, I only drew a few diagrams to understand the data better, but now I have learned other important concepts, such as the relationship between features and their clustering. I recommend it to others!
