Data analysis is a series of steps that take the raw data and transform it into information that can help guide your business operations and decision-making. It starts with identifying the issue you are trying to solve, then gathering all relevant data, and then analyzing the data using various statistical techniques to find patterns or connections. The result is often an increase in profits or efficiency.

You must first identify a goal. This could be as simple as a specific sales goal or as complicated as predicting the likelihood of customer churn. You will then have to decide on which kind of data analysis you will use to achieve your goal. Diagnostic data analysis seeks to find known relationships between data points in order to explain the observations. Predictive modeling is the opposite. It makes use of past data to predict the outcome.

The next step is to collect the data, which can include obtaining it from internal sources, such as CRM software or internal reports and archives. Importing external data may also be required, which entails dealing with data in a variety of formats from various sources. Once you have the data, you can begin to prepare it for analysis by organizing and cleaning it, changing it if necessary and analyzing it using diverse statistical techniques.

After the data has been analysed then write a report that will present the findings in a format that is easy to comprehend by your readers. This may require you to write in a way that is accessible to lay people, or collaborate with a statistician in order to translate technical terminology and procedures into understandable content.
