Exploratory data analysis or EDA is a method deployed by data scientists to analyse and investigate data sets, and summarise their main characteristics, often employing data visualisation methods.
Exploratory data analysis allows the effective manipulation of data sources, assisting data scientists in checking assumptions and hypotheses and discovering data patterns.
Today, we list the top online exploratory data analysis courses available:
Mastering Exploratory Data Analysis: ADaSci
Offered by the Association of Data Scientists, this workshop is meant for learners who want to master data analytics– from the basics to advanced level. On completion of this workshop, one will have an in-depth understanding of data analysis techniques and of the different analysis methods; and will acquire hands-on experience in statistical analysis of data and data visualisation using Python.
The full-day workshop will be addressed by Vaibhav Kumar. The prerequisites of taking this course include knowledge of Python and statistics, and some familiarity with Jupyter/Colab Notebooks.
