The field of Data Science is filled with wonderful applications. In this modern era of digitization, Data Science is making a huge difference in making businesses successful. Not only in business but fields like healthcare, aeronautics, robotics, medicine, etc., Data Science is the game-changer.

Consider watching this video to upskill yourself in the field of Data Science:

1. Education

From earlier civilizations, education has been one of the key aspects of transforming the lives of people. It has helped innumerable people shape their careers and succeed in their lives. Now, education is one of the sectors where Data Science is making drastic changes in improving the entire system and the performance of students, teachers, and other key stakeholders. For example, with Data Science, the data of teachers such as their qualifications, student ratings, the effect of their teaching on the improvement of exam results, etc. are collected, analyzed, and used for further performance enhancement.

Next, the data of students such as the previous result, the current result, marks in individual subjects, etc. can be made useful for analysis. They are collected and then, with the help of Data Science tools for analysis and visualization, we try to extract valuable information to understand the scope for improvement.

When we talk about education, we cannot skip mentioning generative AI tools like ChatGPT, and Google Gemini that are changing the way students used to learn. Today, if students come across any doubt, they can prompt their query and the gen-AI tools will help them understand the feasible solutions.

Here are a few more areas of education that data science is providing resolve for:

  • Students can be provided with custom study plans by analyzing factors such as their scores, interest areas, faculty reviews, etc.
  • Data Science is helping educators design course curriculum as per the analysis of students’ IQ level and performance.
  • Institutes can track the performance of faculties based on student reviews, results of students, improvements by the weak students, etc.

Data Science application is thus helping a lot in improving the current education system.

2. Airline Route Planning

One of the areas where Data Science is revolutionizing day-to-day business activities is the Airline industry. For a very long time, the Airline industry has been bearing a substantial decline in revenue generation, and then Data Science emerged as a savior. Previously, due to competition, the airline companies used to provide discounts to customers to attract them. Also, due to the high rates of fuel and the lack of proper analysis for the delay of flights, destinations, halts, optimized routes, etc., airlines were unnecessarily spending a lot on extra fuel.

To give you an example, Southwest Airlines used data science practices to minimize fuel consumption by strategically analyzing past fuel usage data. They created 8 predictive models that used time-series techniques and neural networks to produce 9600 projections for monthly fuel usage. (Source : NASSCOM Community)

Similar to the above example, with the help of the application of Data Science, many airline agencies have started analyzing the data of their business to strategically improve the sectors, due to which they were bearing heavy losses. Data Science has helped airlines in the following ways:

  • Identifying potential customers to offer calculated discounts, instead of providing discounts to everyone
  • Deciding on the optimized routes by analyzing the traffic on different routes. It helps in saving expensive fuel that gets unnecessarily exhausted otherwise
  • Predicting delays in flight
  • Setting the cost of flights as per seasons, festivals, and the number of travelers. This is done by analyzing the number of potential travelers and frequent travelers
  • Creating new routes to generate more revenue for the airline companies

This is how the application of Data Science is optimizing the profits of the airline industry.

5. Banking and Finance

As we all know, the sector of banking and finance is prone to financial fraud and theft. This happens due to the lack of proper analysis of customer data. Since there are millions of records of customers in databases, it becomes a difficult task to track all of them.

This is where the application of Data Science in banking and finance comes into the picture. It helps organizations efficiently process data.

By processing the data, the system can analyze individual customers’ financial history, loans, income, and debt clearance. Data science helps in finding suspicious behaviors in transactions using fraud detection algorithms. Further, the application of Data Science in Finance helps in the following ways:

  • Stamping out Tax Fraud: The economy of a nation depends on its taxpayers. Governments need taxation to maintain the economic infrastructure of countries. If there occurs fraud activity related to taxation, then it directly affects every citizen of a nation. Therefore, governments have started implementing Data Science to analyze citizen data to prevent tax fraud. With the application of Data Science, the income tax departments keep track of the income and calculate the tax. If the calculated tax is not collected, they track the suspicious taxpayers to take action against them.
  • Credit Scoring: Credit scoring in data science is a statistical technique used in the banking industry to assess the creditworthiness of individuals applying for loans or credit. It involves analyzing various factors such as credit history, income, debt-to-income ratio, and payment patterns to assign a numerical score that represents the likelihood of the borrower repaying their debt. The credit scoring range typically varies from 300 to 850, where higher scores indicate lower credit risk and vice versa. Lenders rely on credit scores to make informed decisions about approving or denying credit applications and setting interest rates.

Apart from the above-discussed applications of Data Science in banking and finance, banks use data to identify their potential customers. They provide certain benefits to their potential customers to maintain a lifetime customer relationship.
