Data analysis is the process of transforming raw data into meaningful, actionable information. You can think of it as a type of business intelligence, which is used to solve problems and other problems within an organization. It’s all about finding patterns in a dataset that can tell you what’s important and relevant to a particular part of the business—how groups of customers behave, for example, or why sales fell at a given time.
A data scientist takes the data generated and analyzes it to gain valuable insights. They then present this information in visual forms, such as graphs and charts, so that stakeholders can understand and act on it. The types of information extracted from the data depend on the type of analysis performed. There are four types of analysis used by data scientists:
Descriptive analytics looks at what happened in the past, while descriptive analytics looks at why it might have happened. Predictive and predictive analytics consider what will happen in the future and, based on these predictions, what the best course of action would be.

Overall, data analysis helps you understand the past and predict future trends and trends. So, instead of basing your decisions and strategies on guesswork, you’re making informed decisions based on what the data is telling you. With a data-driven approach, businesses and organizations can gain a deeper understanding of their audience, their industry, and their company as a whole—and, as a result, are better equipped to make decisions, plan for the future, and compete in their chosen market.
Any organization that collects data can use data analysis, and how it is used will vary depending on the situation. In short, data analysis is used to drive intelligent business decisions. This helps reduce business costs, create more efficient products and services, and improve processes and operations throughout the organization.
Specifically, data analysis can be used to predict future sales and purchases, for example by identifying past trends. It can be used for security purposes, for example, to detect, predict, and prevent fraud, especially in the insurance and financial industries. It can be used to evaluate the effectiveness of marketing campaigns, and improve audience targeting and personalization. In the healthcare sector, data analytics can be used to make quick, accurate diagnoses and identify the most appropriate treatment or care for each individual patient. Data analysis is also used to optimize general operations, for example by identifying and removing bottlenecks within certain processes.
Data analytics is used in almost every industry – from marketing and advertising to education, healthcare, travel, transportation and logistics, finance, insurance, media and entertainment. Think about what you like about what you get from Netflix and Spotify; everything is under data analysis. You can learn more about how analytics are used in the real world here.

The data analysis process can be divided into five stages: Defining the question, collecting data, cleaning data, analyzing, creating visualizations and sharing information.
The first step in this process is defining a clear goal. Before you start analyzing data, you come up with a hypothesis you want to test, or a specific question you want to answer. For example, you might want to find out why many customers unsubscribed from your email newsletter in the first quarter of the year. Your problem statement or question will inform what you analyze, where you draw from, and what type of analysis you do.
With a clear goal in mind, the next step is to gather the right data. You can get your data from an internal database or from an external source – it all depends on your goals.
Next, you will prepare for the analysis, removing anything that may interfere with the interpretation of the data – such as duplicates, errors, or missing data. This can be a time-consuming task, but it is an important part.

This is where you start to draw more information from your data. How you analyze data depends on the question you’re asking and the type of data you’re using, and there are many different methods available to you, such as trend analysis, cluster analysis, and time analysis (to name a few).
The final stage is where the data is transformed into useful and actionable information. You will present your findings in the form of charts and graphs, for example, and share them with stakeholders. At this point, it’s important to explain what the data tells you about your original question. You’ll find a complete guide to data visualization in this guide.
Many companies are collecting massive amounts of data all the time—but, in its raw form, this doesn’t mean anything. A good communicator interprets what happened to make sense of it and presents it in a way that is easy for everyone to understand. Therefore, data analysts play a vital role in any organization, using their data to drive smart business decisions.
Data analysts are employed in a variety of industries, and the role can vary greatly from one company to another. For example, a typical day for a medical technician working in a hospital will be very different from a typical day for a technician at an insurance company. This diversity is part of what makes data analysis such an exciting career path.
