Data Science Case Studies

After exploring the different Data Science applications, let us see some of the case studies that will illustrate how Data Science plays a significant role in the betterment of these fields.

1. Transport for London – Data Science Case Study

In London, there is an organization named Transport For London (TFL) that looks after the connectivity of trains, cars, and other means of transport.

The current population in London is more than 8.5 million.

Lauren Sager Weinstein, the Data Analytics Head at TFL realized the importance of Big Data to provide better services to all the travelers by efficient planning of different transport services.

The data for this purpose is collected from different sources such as ticket systems, maps, etc.

TFL used this data to improve their services and provide 24×7 comfort to the passengers. It also provides online services to travelers.

TFL analyzed the collected data in many different ways and came up with such meaningful insights that helped them to manage traffic effectively and discover alternate routes.

2. American Cancer Society – Data Science Case Study

One of the research performed by the American Cancer Society in 2017 states that nearly 1.7 million people in the US were expected to be diagnosed with Cancer.

Over 600 thousand people died because of Cancer, that is, 1650 per day.

Importantly a huge number of these cases can be easily prevented if people would change their behavior.

For example, by stopping smoking, eating better or by using sun-screen. This lets you know that there is a space for research in terms of things that can predict Cancer.

It also provides a better understanding of how Cancer operates and how Data Scientists can help Cancer Physicians to develop better methods of treatment.

The early detection of cancer is critical.

Some common forms of cancer such as Breast Cancer, Prostate Cancer, etc. have a survival rate of around 100% if they are caught and treated early, that is, for the stage one but the survival rate is 30% if they are caught in stage four, that is, the most serious stage.

As a result, Data Scientists are working closely with medical researchers to find methods to identify Cancer as soon as possible with chances of improvements in the survival rate for everyone.

University of Toronto Research

For instance, research at the University of Toronto has worked with the development of a microchip that can detect the basics of many forms of cancer such as Brain Cancer, etc. which are difficult to detect until they become too advanced.

Developing this chip might find ways of sorting through the data within the chemical sample from the blood to give people a better clue on how they can recover sooner.

Also, researchers from the field of Computer Science and Artificial Intelligence are developing Machine Learning models to differentiate between various forms of cancer to ensure that patients receive the right treatment.

They are not only improving accuracy with their model but they are also making special efforts to ensure that their model is transparent and convenient by practicing it with physicians.

Data Science has also contributed to important advances in the Science of Cancer, that is, the research that gives a basic understanding of how the disease operates and how we can defeat it.

It combines insights from the data with the Data mining of existing drugs to find effective drugs for cancer treatment.

Data Science also helps the doctors to schedule the treatment based on the patient’s data.

Providing the right treatment at the right time is the most important and difficult thing.

But, Data Science has helped by improving the existing treatments and making them more available for the patients.


Thus, Data Science has grown unbelievably and has significant effects on almost every field.

Various industries like Finance, E-Commerce, Travel, Healthcare, etc. are using Data Science to meet the requirements of the market as well as the users.

The industries are using Data science for improving their products and for producing the most profitable results by using a large amount of data available.
