Data Wrangling and Visualization

Learn various techniques for data wrangling and visualization.

Course details

Reshaping data is an important component of any data wrangling toolkit as it allows the analyst to “massage” the data into the desired shape for further processing. As we go through a comprehensive process in uncovering pandas capabilities, we will learn more adept techniques in working with data in this 12-hour course.

The Data Analytics Specialization is a 4-week bundle that is curated to accelerate a student’s mastery in building data products, develop a web application, and data visualization.

Students are not assumed to have a working knowledge of Python or prior proficiency in statistics/mathematics/algebra. As such the workshop follows a gentle learning curve and emphasizes hands-on, one-to-one tutoring from our team of instructors and teaching assistants.

Learn data analysis by building:

Students work through tons of real-life examples using sample datasets donated by our team of mentors and corporate partners. We believe in a learn-by-building approach, and we employ instructors who are uncompromisingly passionate about your growth and education.

Part of Data Analytics Specialization

This course is part of the Algoritma Data Analytics Specialization. Participants are rewarded with a certificate of completion upon passing criteria.
