Data is dynamic and highly influential and organizations all around the world recognize the significance that data analytics holds a potential role when it comes to fostering organizational growth and profitability. The importance of data analytics has increased more even in today’s business environment. In order to meet consumer demand, data mastery skills are necessary so that useful information can be extracted by using various AI tools from both structured and unstructured data which makes data analytics course a vast field. In this article, we are going to provide the details of the Data Analytics courses at NPTEL.
What is Data Analytics?
Data is the foundation of everything, if you want to explore something, what is the first thing you need that is data. Data analytics is the process of using data, methods, and tools to spot patterns and trends that lead to practical knowledge that can be used to make decisions. Data analytics’s main goal is to tackle specific issues or problems that are pertinent to a company in order to improve business outcomes or can lead to decision making which is necessary for the smooth functioning of the organization.
It is the study of analyzing unprocessed data to draw inferences about information. Numerous methods and procedures used in data analytics have been streamlined into mechanical procedures and algorithms that operate on raw data for human consumption. Making data-informed strategic decisions is essential in the business and workforce landscape of today.
Understanding how to use data effectively can be very beneficial for any organization, whether its goals are to better understand its customers, streamline operations, or create new business prospects. The demand for the data analytics field is tremendously increasing which makes this field very important to opt for. Data analytics can be applied to different fields like healthcare, insurance, finance, sports, industries, retail, and the list goes on.
Types of Data Analytics?
Data analytics is generally of four types, which are as follows:
Descriptive Analytics: This summarises or explains what has occurred over a specific time frame. For example: if we talk about Instagram, then we see that our views increased as compared to the last month, is the graph going up or down?
Diagnostic Analytics: This is more concerned with the reasons behind events that have occurred. More varied data inputs are used, along with some speculation. For example: if we take the example of Instagram, what is the reason behind the views going down? Which content needs alteration?
Predictive Analytics: This section deals with what will probably occur soon. These methods analyze historical data to spot trends and assess their likelihood of recurrence. For example: How is the audience going to perceive the content according to the content shared in the past on Instagram?
Prescriptive Analytics: This suggests an approach or what action should be taken. For example: we should collaborate with an ad agency in order to get more viewers according to the past history showing the viewers viewed the content on Instagram.
Various Steps Followed in Data Analytics
Data analysis covers a number of steps, including:
Problem Identification: The first step in the analytics process involves comprehending the company’s problems, defining the organizational goals, and planning a profitable solution. The challenges that e-commerce businesses face include anticipating product returns, making relevant product recommendations, canceling orders, spotting fraud, optimizing truck routing, etc.
Identification or grouping of data: Identifying the data needs or how the data is grouped is the first stage. Data might be categorized based on gender, income, age, or other factors. Data values might be numerical or categorical.
Collection of data: The process of gathering data is the second phase in data analytics. There are a number of sources or equipment, including computers, the internet, cameras, environmental sources, and human employees, that can be used to accomplish this data collection process.
Data arrangement or organizing: After being gathered, the data needs to be organized in order to be analyzed. A spreadsheet like Excel or another piece of software like SPSS that can handle statistical data may be used for this.
Correction of errors before implementation: After that, the data is cleaned up for analysis. It gets cleaned up and reviewed to make sure there are no duplicates, errors, or missing information. This phase assists in removing any inaccuracies before the data is sent to a data analyst for analysis.
Data exploration and analysis: Implementing exploratory data analysis is the next crucial step after collecting the appropriate data. To analyze, visualize, and forecast future effects from this data, employ business intelligence tools, data mining techniques, and predictive modeling. By using these data exploration techniques, you can ascertain the impact and relationship between a particular attribute and other variables.
Interpret the results: The results must be interpreted in order to determine whether the outcomes live up to your expectations. After interpreting the results, you might discover occult patterns and upcoming trends, which will help to make data-driven decisions.
Why Does Data Analytics Need to Be Studied?
After looking at what data analytics is, let’s discuss some applications for it and why it is necessary to be studied.
Helps in better decision-making: Manual labor and guesswork are eliminated by data analytics. It helps in developing the right content, generating or setting market campaigns, or product development. Businesses can leverage the insights uncovered by data analytics to help them make better or more informed decisions.
More effective customer service: You may customize client service to meet their needs using data analytics. Additionally, it adds personalization and strengthens connections with clients. It enables you to make suggestions for goods and services that are better which is necessary for growth and profitability.
Efficiencies in operations: You can improve production, reduce costs, and streamline business processes with the use of data analytics. You might spend less time creating advertisements and other content that doesn’t appeal to your audience if you have a better understanding of what they want.
Constructive or successful marketing: You can learn a lot about the effectiveness of your efforts via data analytics Furthermore, you can figure out which prospective clients are most likely to affix themselves to a campaign and develop into leads.
Sectors of Data Analytics?
Let’s examine a few of the commercial fields where data analytics is applied:
IT Sector: The IT sector holds the largest market share for the data analytics sector. Due to the great innovation in the IT sector, the demand for the data analytics sector makes it a great career to pursue.
Banking and Financial Sector: This sector is the second largest sector. Banking and Financial Sectors have used AI and data analytics to expand their businesses.
