The Basics of Data Analysis

Data analysis is the process of turning data into information that can help you make better business decisions and operations. It starts by identifying the issue you wish to solve, collecting the relevant information, and then analyzing it using diverse methods of analysis that reveal the underlying patterns or connections. The result is usually increased profitability or efficiency.

To begin the process, you need to define a target. The goal can be as simple as as predicting customer churn. Then, you must decide on the type of data analysis will lead you there. Diagnostic data analysis attempts to determine the relationships between data points to explain the observations. Predictive modeling on the other hand utilizes past data to predict outcomes.

The next step is obtaining the data, which can include obtaining it from internal sources like CRM software or internal reports and archives. Importing external data could also be required, which requires processing data in different formats from different sources. Once you have the data you can begin preparing it for analysis by organizing and cleaning it, then changing it as needed and then analyzing it using various statistical techniques.

After the data has been analyzed, write a report to provide the results in a manner that is easy to comprehend for your readers. This could require you to write for laypeople, or collaborate with a statistician translate technical terms and procedures into usable content.
