Exploratory Data Analysis: A Guide with Examples

Mlearning.ai

Before conducting any formal statistical analysis, it’s important to conduct exploratory data analysis (EDA) to better understand the data and identify any patterns or relationships. EDA is an approach that involves using graphical and numerical methods to summarize and visualize the data. We can use summary statistics to do this.

Hypothesis Testing in Action: We learned how to formulate a null hypothesis (no difference exists) and an alternative hypothesis (a difference exists) and use statistical tests to evaluate their validity. EDA involves techniques like: Identifying different types of variables (categorical, numerical).

Exploratory data analysis The purpose of having an EDA layer is to find out any obvious error or outlier in the data. are captured and compared by formulating a hypothesis test to conclude with statistical significance. In this layer, we need to set up a set of visualisations to monitor statistical parameters from the data.
