I am sharing my journey of #66DaysofData into Data Analytics by participating in Ken Jee's #66daysofdata challenge
Data Analytics is the process of exploring and analyzing large datasets to find hidden patterns, unseen trends, discover correlations, and derive valuable insights to make business predictions.
It helps in Improved Decision Making, Better Customer Service, Efficient Operations, Effective Marketing and Improves the Speed and Efficiency of the business.
Businesses use many modern tools and technologies to perform Data Analytics.
