The Basics of Data Analysis

Data analysis is a series of steps that gather raw data and transform it into insights that guide your business operations and decision-making. It starts by identifying the issue you wish to solve, gathering the relevant data, and then analyzing it using various methods of analysis that reveal the underlying patterns or relationships. The result is often an increase in profit or efficiency.

First, you need to identify a goal. This goal could be as simple or complex like predicting churn among customers. You must then decide which kind of 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, on the other hand, uses past results to predict outcomes.

The next step involves obtaining data. This may require collecting data from sources like CRM software, internal reports, and archives. It may also involve importing external data, which involves working with data from multiple sources in a variety of formats. Once you have the data you can begin to prepare it for analysis by cleaning and organizing it, changing it if needed and analyzing it using various statistical methods.

After the data has been examined after which you write a written report to present the findings in a format that is easy to comprehend by your readers.
