The Primary Goal of Exploratory Data Analysis (EDA) in Data Science
Exploratory Data Analysis (EDA) plays a crucial role in the field of data science. It involves the initial exploration and analysis of data to gain insights and understand the underlying patterns and relationships. The primary goal of EDA is to determine whether a predictive model is a feasible analytical tool for business challenges or not.
Why Is EDA Important?
EDA is important because it helps in understanding the data and identifying any issues or anomalies that may affect the accuracy and reliability of the predictive model. It allows data scientists to gain a deeper understanding of the dataset and make informed decisions about the data preprocessing and modeling techniques to be used.
Why Do We Perform Exploratory Data Analysis?
Exploratory Data Analysis is performed to:
- Identify missing values and handle them appropriately
- Identify outliers and decide whether to remove or transform them
- Identify the relationship between variables and determine their significance
- Identify patterns and trends in the data
- Identify and handle multicollinearity
- Identify and handle class imbalance in classification problems
Objective of Exploratory Data Analysis
The objective of EDA is to gain insights into the data and understand its characteristics, such as central tendency, dispersion, distribution, and correlation. This helps in making informed decisions about data preprocessing and modeling techniques.
Conclusion
Exploratory Data Analysis (EDA) is an essential step in the data science process. Its primary goal is to determine whether a predictive model is a feasible analytical tool for business challenges or not. EDA helps in understanding the data, identifying issues, and making informed decisions about data preprocessing and modeling techniques.
