Data Pre-Processing for Data Analytics and Data Science

Data Pre-Processing for Data Analytics and Data Science, Pre-Processing for Data Analytics and Data Science.

Course Description

The Data Pre-processing for Data Analytics and Data Science course provides students with a comprehensive understanding of the crucial steps involved in preparing raw data for analysis. Data pre- processing is a fundamental stage in the data science workflow, as it involves transforming, cleaning, and integrating data to ensure its quality and usability for subsequent analysis.

Throughout this course, students will learn various techniques and strategies for handling real-world data, which is often messy, inconsistent, and incomplete. They will gain hands-on experience with popular tools and libraries used for data pre-processing, such as Python and its data manipulation libraries (e.g., Pandas), and explore practical examples to reinforce their learning.
