Data analysis is a series of steps that gather raw information and transform it into insights that guide your business’s activities and decision-making. It begins with identifying the problem you want to solve, collecting the relevant data, and then analyzing it using various techniques of statistical analysis to find the root patterns or connections. The result can be improved efficiency or profitability.

First, you must establish your goal. This goal could be as simple or as complex like predicting customer churn. It is then up to you to decide what type of data analysis will employ to reach your target. Diagnostic data analysis is designed to discover known connections between data points in order to explain observations. Predictive modeling on the other hand, uses past results to predict outcomes.

The next step is obtaining data. This may require collecting data from sources like CRM software, internal reports, and archives. It could also include importing external data, which requires dealing with data from various sources in different formats. Once you have the data you can begin to prepare it for analysis by cleaning and organizing it, then changing it if necessary and then analyzing it with different statistical techniques.

After the data has been examined and analyzed, you need to create a summary of the results and presents them in an easy-to-understand format for your readers. This may require you to write for laypeople or collaborate with a statistician to translate technical terms and procedures into readable content.
