What are the main methods of Data Analysis?

The question is about data analysis

Answer:

Some of the main techniques of Data Analysis include Descriptive Analysis, which summarizes data to understand trends; Inferential Analysis, which makes predictions about a population based upon a sample; Exploratory Data Analysis, which discovers patterns and relationships through visualization; Predictive Analysis, which uses statistical models to predict future outcomes; Prescriptive Analysis, which provides recommendations on actions or decisions; and Qualitative Analysis, in which non-numeric data is studied to identify themes.

These come into play depending on the goals, all the way from understanding the current data to trend prediction and decision guidance.
