Descriptive statistics provide simple, quantitative summaries of datasets, usually combined with descriptive graphics. After data collection, the first step is to get basic information of the data using descriptive statistics. This provides easy-to-understand information that helps answer basic questions based on the average, spread, deviation of values and so on. They give analysts a rough idea about what the data is indicating so that later they can perform more formal and targeted analyses.

What is a Scatter Plot – Overview, Definition, Graph & Examples
we will learn about scatter plots, which are simple plots giving us insights into trends of the data. We will go deeper with some advanced features that make scatter plots an invaluable gift for effective data visualization.
What is EDA? Importance, Types & Tools of Exploratory Data Analysis
EDA helps data scientists to manipulate data sources to get the answers they need, and as a result making the data analysis process easy for discovering patterns, testing a hypothesis, spotting anomalies, or checking assumptions.
Exploratory Data Analysis using Data Visualization Techniques!
We can define exploratory data analysis as the essential data investigation process before the formal analysis to spot patterns and anomalies, discover trends, and test hypotheses with summary statistics and visualizations.
