What is Data Analysis
Data analysis is a process of treating raw data with the goal of extracting useful information in order to form conclusions and support decision-making.
A variety of statistical techniques can be used to interpret, describe, represent, evaluate, and organise data. Data analysis involves logical and analytical reasoning to examine each component of the collected data.
The main types of data analysis are data mining (discovering patterns in large data sets, such as in Business Intelligence), statistical analysis, diagnostic analysis (identifying the causes of data patterns), predictive analysis (for predicting future outcomes), and prescriptive analysis (which combines different analyses to influence decision-making).
