We live in an era with an exploding amount of data surrounding us. Every day or even every second, data is generating non-stop and fast. To deal with such a massive amount of data, we need to know how to analyze data and extract valuable insights. This is where statistical data analysis comes into play. It is used by scientists, governments, businesses, and organizations to investigate trends, patterns, and relationships in data, and thus it is necessary for many in-demand data analytics job roles. Statistical data analysis is an indispensable part of any data analysis task with a professional statistical attitude toward data. It is used whenever we need to decide on research design, sample size, and sampling technique, as well as specify hypotheses for testing variables relationships.

TechClass Statistical Data Analysis with Python online course aims to provide a rich data analysis skill-set to help you grasp knowledge and insights within data. It 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.
