What is the difference between Data Analysis and Data Mining?
Data Mining is a combination of statistics, statistics, visualization, information science and machine learning. We create probability distributions using descriptive statistical methods and inferential statistics to obtain estimation, hypothesis testing, model scoring & generalized models classes.
It contains a large structured database that the data scientists and analysts use to identify data patterns and trends.
