What Is Data Analysis In Brief
Data analysis is the structured procedure that involves working with data by performing activities such as ingestion, cleaning, transforming, and assessing it to provide insights, which can be used to drive revenue.
Data is collected, to begin with, from varied sources. Since the data is a raw entity, it has to be cleaned and processed to fill out missing values and to remove any entity that is out of the scope of usage.
After pre-processing the data, it can be analyzed with the help of models, which use the data to perform some analysis on it.
The last step involves reporting and ensuring that the data output is converted to a format that can also cater to a non-technical audience, alongside the analysts.
