It is a fatal error to theorize before having data." "Insensibly, one begins to modify facts to suit hypotheses, rather than ideas to suit facts," declares Sherlock Holme in Sir Arthur Conan Doyle's A Scandal in Bohemia.


This concept is at the heart of data analysis. We can make better decisions when we can extract meaning from facts. And we live in an era where we have access to more data than ever before. The World Economic Forum's Future of Jobs Report 2020 ranked data analysts and scientists first, followed by AI and machine learning specialists and big data specialists.  This blog will teach you more about the data analysis method, different types of data analysis, and courses to help you get started in this exciting field.


What is Data Analytics


Although numerous people, companies, and specialists approach data analysis in different ways, the majority of them may be reduced into a one-size-fits-all description. Data analysis is the process of cleansing, transforming, and analyzing raw data in order to obtain usable, relevant information that assists businesses in making educated decisions. The technique reduces the risks associated with decision-making by offering relevant insights and statistics, which are frequently displayed as charts, graphics, tables, and graphs.


When we make a decision in our daily lives, we evaluate what has happened in the past or what will happen if we make that decision, which is a simple example of data analysis. This is essentially the process of assessing the past or future and making a decision based on that understanding.


Data analytics is a broad phrase that incorporates a wide range of data analysis techniques. Data analytics techniques can be applied to any type of information to gain insight that can be utilized to improve things. Data analytics approaches can uncover trends and indicators that would otherwise be lost in a sea of data. This data can then be utilized to streamline procedures and boost a company's or system's overall efficiency.


The term "big data" is frequently mentioned in conversations concerning data analysis. Data analysis is critical in transforming huge data into valuable knowledge. Beginner data analysts who want to delve deeper by addressing big data basics should start with the fundamental question, "What is data?" Simplilearn's non-coding courses will help you find new job prospects. Learn useful skills, explore many domains, and thrive in the digital age. It might be challenging to determine specific metrics or key performance indicators (KPIs) from data. Getting integrated information in a timely manner can be difficult when data is dispersed throughout an organization. Getting the information or insights your company requires to succeed takes too long and requires too much effort.


This is frequently due to a potential lack of analytics skills. The data is readily available, but there is no technology that allows for quick access. If there was, data or business analysts may perform self-service data visualization and analysis in real time. Again, the data is frequently dispersed, necessitating laborious data collection before personnel can begin their study. It may be difficult to extract specific metrics or key performance indicators (KPIs) from data. When data is distributed throughout an organization, it might be challenging to obtain integrated information in a timely manner. Obtaining the information or insights required by your firm to succeed takes far too long and needs far too much effort.


This is often attributed to a possible lack of analytics expertise. Although the data is easily available, there is no technology that allows for immediate access. If there was, data or business analysts could undertake real-time self-service data visualization and analysis. Again, the data is widely spread, needing time-consuming data collection before workers can begin their research.


Types of Data Analysis


Data can be utilized in a variety of ways to answer questions and assist choices. It can assist to become acquainted with the four forms of data analysis typically employed in the area in order to determine the best technique to examine your data.


In this section, we'll look at each of these data analysis approaches, as well as an example of how each may be used in practice.


  1. Analyze descriptively:


Descriptive analysis explains what occurred. This sort of study uses statistics to describe or summarize quantitative data. Descriptive statistical analysis, for example, might indicate the distribution of sales among a group of employees as well as the average sales figure per employee.  Descriptive analysis provides an answer to the inquiry, "What happened?"


  1. Diagnostic evaluation:


Diagnostic analysis determines the "why" after descriptive analysis establishes the "what." Assume a descriptive study reveals an unusually large influx of patients in a hospital. Further investigation of the data may indicate that many of these individuals shared symptoms of a specific infection. This diagnostic investigation can assist you in determining whether an infectious agent—the "why"—was responsible for the surge of patients. Diagnostic analysis provides a solution to the query "why did it happen?"


  1. Predictive modeling:


So far, we've looked at analysis types that investigate and draw judgments about the past. Data is used in predictive analytics to make predictions about the future. Using predictive analysis, you may see that a particular product has had its strongest sales between the months of September and October each year, leading you to expect a similar high point during the following year. Predictive analysis provides a solution to the question, "What could happen in the future?"


  1. Prescriptive evaluation:


Prescriptive analysis employs all of the insights gained from the previous three forms of analysis to make suggestions for how a corporation should proceed. Using our previous example, this type of analysis could recommend a market strategy to capitalize on the success of the high sales months while identifying fresh growth prospects in the slower months. Prescriptive analysis provides a response to the question, "What should we do?" The concept of data-driven decision-making comes into play in this last type.



Why is Data Analysis Important?


Historically, comparing statistics and analyzing data for business insights was a laborious, time-consuming process that relied heavily on spreadsheets. Businesses began to leverage electronic technology, such as relational databases, data warehouses, machine learning (ML) algorithms, web searching solutions, data visualization, and other tools with the ability to facilitate, expedite, and automate the analytics process, beginning in the 1970s.


However, along with technological advancements and increased market demand, new problems have emerged. An increasing number of competitive, and sometimes incompatible, analytics and data management solutions resulted in technology silos, not only within departments and organizations, but also with external partners and vendors. In addition, some of these solutions are so complex that they need technical expertise above that of the average business user, limiting their applicability within the industry.


You are probably aware that good data analysis is utilized to make better business decisions. But what exactly does that mean? Many decisions are made within a firm. What is the purpose of data analysis? Lets try and understand why is data analysis important for your firm:


  1. Informed decision-making:


From a management standpoint, reviewing your data can help you make decisions based on facts rather than mere intuition. For example, you can learn where to invest your money, identify development prospects, forecast your income, and deal with unusual events before they become problems. This allows you to pull key insights from all sections of your organization and present the data to various stakeholders in a professional and interactive manner using dashboard software.


  1. Product Creation:


Businesses that manufacture a product or provide a service rely on customer data to identify what steps to do next. E-commerce enterprises, for example, have a large pool of potential clients. They use demographic data, historical purchase data, and even payment data to determine which products and services are appealing to various groups of individuals.


  1. Specified Content:


Content is huge in the digital age, and businesses are ramping up their game. Marketing campaigns and pricing strategies might benefit from quality data. Learning what your customers want can also inspire your social media content and lead to further efforts such as webinars, events, and partnerships.


  1. Minimize costs:


Another significant advantage is the ability to minimize costs. Businesses can identify improvement possibilities, trends, and patterns in their data using advanced technology such as predictive analytics and plan their plans accordingly. This will eventually save you money and resources spent on executing ineffective strategies. Not only that, but by forecasting various situations such as sales and demand, you can also forecast production and supply. 


  1. Improved customer targeting:


Customers are undoubtedly the most important aspect of any business. You can discover the channels your consumers use to connect with you, their demographics, interests, habits, purchase behaviors, and more by employing analytics to gain a 360° view of all aspects relating to your customers. It will help your marketing efforts succeed in the long run by allowing you to identify new potential customers and prevent wasting resources on targeting the wrong individuals or sending the wrong message. You can also track customer happiness by examining client reviews or the effectiveness of your customer service department.




Millions of manually prepared spreadsheets are utilized in fields ranging from finance to science to economics. Nonetheless, 90% of all spreadsheets have flaws that affect their output, according to ZDNet. Businesses have lost millions of dollars due to cut-and-paste errors, concealed cells, and other blunders.


Traditional analytics tools and methods can sometimes cause delays in providing businesses with the information they require to make timely choices. Data is frequently collected from numerous


In a world that is more reliant on information and statistics, data analytics assists individuals and companies in ensuring the accuracy of their data. A set of raw numbers can be converted into instructive, educational insights that drive decision-making and deliberate management using a range of tools and methodologies.


Everything may be automated when using a modern analytics solution. Determine a few parameters for what you want to analyze, which model to use, and which column to predict, and the answer will take over. Data can be collected from a variety of apps, platforms, and clouds. It can be automatically gathered, cleaned, processed, transformed, and evaluated for predictions, thereby speeding up processing and lowering the possibility of human-caused errors.
