Data Analytics is the domain of science of analyzing the raw data so as to draw fruitful conclusions based on that information. It is a science that helps the individuals and companies make out sense of the raw data and then deliver insights and trends based on it. It is a vast process involving steps like inspecting the raw data, cleansing it, then transforming it, followed by modelling the raw data with the aim of discovering some useful information, presenting conclusions and then supporting in the decision-making process. Data Analytics use various tools, techniques and algorithms that help the individuals or organisations make useful insights and succeed. There are various types of Data Analysis including the prescriptive, diagnostics, descriptive and predictive analysis.

What exactly is Data Analytics?

Data Analytics is the discipline of science that focuses on extracting insights from the raw data, and also includes the collection, analysis, organization and storage of the data.

The seemingly endless applications and the advantages that the Data Analytics has had, has clearly revolutionized the world. More and more data are created each day, collected and then Data Analytics is applied so as to create new opportunities for various parts of business, science, research and everyday life.

How does Data Analytics work?

Data Analytics is strategy-based science domain where raw data is analyzed to detect trends, answer various questions and draw conclusions from that large amount of data. The Data Analytics has various steps involved in the working. They are: 

  1. Data Requirement

    For making Data Analytics to work, first it is important to decide what kind of data the process is to be carried out on. As for different data the conclusion would differ. For instance, one might want the process to work for detection of population of a city, for other it may be to calculate marks of a certain group of students, and so on.

  2. Data Procurement

    The next step involves Data Procurement. Here, proper data collection is necessary because if the data collection is not proper then the results would differ accordingly. So, its utmost important to make accurate data collection so as to get the most precise and accurate results for the data collected.

  3. Data Processing

    After the Data Collection is done, next step is the Data Processing. Here the gathered data is to organized and analyzed for the further processing. Proper data organization too is required as if not done, it might also result in some sort of result inaccuracy.

  4. Data Cleansing

    The Data collected at all times may not be totally useful. It might have some sort of repetitive elements, or some error may be present in the collected data. So, it is important to either fix certain anomaly or get rid of it. So, at this stage the Data is properly cleansed by either removing or fixing the errors.

  5. Data Analysis

    This is the most important step in the Data Analytics part as at this step the data is analyzed and based on that the conclusions are drawn. Various data analysis tools, techniques and algorithms are used here like Data Visualization, Regression, Classification, Correlation and so on. It may be that even after the Data Cleansing step some anomalies may be present, so it is removed at this step.

  6. Data Communication

    After the Data Analysis step, the data is converted into an organized and simple document form. This is then made useful for taking insightful decisions and for making decisions based on this data. The document presented here may be in the form of graphs, charts, tables, or any other form.
