Data analysis is the process of turning data into information that can aid your business decisions and operations. It begins with identifying the issue you wish to solve, gathering the relevant data, and analysing it using a variety of methods of analysis that reveal the underlying patterns or connections. The result is usually an increase in efficiency or profitability.
First, you must establish the goal. This goal could be as simple as like predicting customer churn. Then, you need to decide which type of data analysis will get you to your goal. Diagnostic data analysis focuses on known connections between data points to explain observations, while predictive modeling relies on past data to predict future outcomes.
The next step is obtaining data. This could mean obtaining it from sources such as CRM software, internal reports, and archives. It could also require importing external data, which involves the use of data from a variety of sources in different formats. Once you have the data, you can begin preparing it for analysis by organizing and cleaning it, changing it if necessary and analyzing it using different statistical techniques.
After the data is analyzed then write a report that will present the findings in a format that is easy to understand for your readers. This may require you to write for laypeople, or work with a statistician to translate technical concepts and procedures into easily understood text.
