Statistical Data Analysis with Python (10 op)

Tavoitteet

Data analysis and statistical analysis are necessary for many in-demand data analytics job roles. They are used hand in hand to solve business problems; data analysis is a general approach to making data understandable for decision-makers, and statistical analysis is a professional statistical attitude. A rich data analysis skill-set will help you better understand the data to extract knowledge and insights. This course is designed to give you the necessary resources to gain the career-building Python skills you need to succeed as a Data Analyst. By the end of this course, you will get a full understanding of how to use Python’s scientific computing libraries to import, clean, manipulate, visualize data and use a wide range of statistical techniques to analyze data to extract meaningful insights.

This course is 100% virtual thanks to the comprehensive tutorial videos and content prepared for this course.

The student will pass this course after submitting the required quiz, assignments, and the final project.
