EDA stands for Exploratory Data Analysis. It is a process used in statistics to analyze and investigate datasets and summarize their main characteristics, often using visual methods. Here are the steps to explain EDA:

1. **Data Collection**: The first step in EDA is to gather the data. This could be through various sources like databases, files, web scraping, APIs, etc.

2. **Data Cleaning**: Once the data is collected, it needs to be cleaned. This involves handling missing values, outliers, and errors in the data. This step is crucial as the quality of data can significantly impact the results.

3. **Data Wrangling or Munging**: This step involves transforming and mapping data from its raw form into another format to make it more valuable for a variety of downstream purposes such as analytics.

4. **Data Analysis**: After the data is cleaned and transformed, it is time for analysis. This involves looking at the data from different angles, digging deeper into the data to find patterns, relationships, or trends. This could be done using various statistical and visualization techniques.

5. **Data Visualization**: This is the process of representing the data in a graphical format. This helps in understanding the data better and gaining insights from it. It could be in the form of bar graphs, histograms, scatter plots, etc.

6. **Insights**: The final step is to draw insights from the analysis and visualization. This could be in the form of understanding the patterns, making predictions, or making decisions based on the data.

In summary, EDA is a critical step in the data analysis pipeline, leading to better understanding of data, superior modeling, and ultimately better business decisions.
