The pandemic has made a significant impact on educational institutes everywhere. Colleges, universities, and institutions have resorted to online classes. Data science is one of the many subjects being taught online now. But this digital way to education has brought more perks than just safety.

Now, more and more people understand how the internet works and data scientists are using their knowledge and experience to teach online. Thanks to this wide range of availability, data science courses have become more accessible for interested students.

If you’re looking for such data science courses online, ExistBI has a wealth of experience and a variety of courses available for all ability levels. We’ll discuss what data science curriculums include and how you can learn online.

Data Science Courses

What Is Data Science About?

Let’s first briefly discuss what data science is and what it involves if you’re new to this concept and the big data industry. Data science utilizes systems, algorithms, processes, and scientific methods to extract necessary information from data. This data could be structured or unstructured. Data science revolves around machine learning and data mining.

In simple words, data science is the extraction of meaningful insights from a piece of data through domain expertise, statistics, and mathematics and programming skills.

What Does A Data Science Course Include? 

The entire course is a blend of various subjects, including:

  • Machine learning
  • Algorithms
  • Tools
  • Jameen expertise
  • Coding
  • Twitter analysis
  • Business acumen
  • Mathematics

The curriculum teaches the scientist how to identify and extract meaningful, useful, sometimes hidden, insights from a collection of raw data.

What Does A Data Scientist Do?

The useful information extracted by a data scientist helps businesses make crucial decisions. Analysis and structuring of raw data can help companies make valuable changes to their strategies, understand their profits and losses, and grow financially. Moreover, by sharing and extrapolating such useful insights, these scientists can help businesses come out of financial crises and solve many problems.

What Are the Major Differences between Data Science and Business Analytics

With the growing availability and accessibility to both these programs, people must learn the difference between them.

So, let’s compare them, shall we?

  • Data science is studying data with the help of technology, algorithms, and statistics. In contrast, business analytics involves statistically analyzing business data to gain insights.
  • Data science utilizes both structured and unstructured data, while business analytics mostly involves structured data.
  • Data science incorporates a lot of coding. It is a perfect blend of excellent computer knowledge and traditional analytics. In contrast, business analytics does not include a lot of coding. It is more oriented towards statistics.
  • In data science, scientists use statistics after finalizing the analysis after coding. In business analytics, however, the analyst completes the entire research on the basis of statistical concepts.
  • Data scientists study almost all kinds of trends and patterns, while business analysts study trends and patterns only specific to businesses.
  • Industries like e-commerce, machine learning, manufacturing, and finance are the topmost applications of data science. These industries are telecommunications, supply chain, marketing, retail, health care, and finance for business analytics.

So, as is evident here, both business analytics and data science are entirely different. Both fields incorporate different strategies, and both types of professionals have varying jobs and opportunities. The point of discussing this comparison was that you should know what you’re getting yourself into and what your opportunities look like. You should always know the difference between two similar professions, especially if you’re trying to pursue one of them.

Leveraging Data Science To Combat Covid-19

Amidst the pandemic, it has come to everyone’s attention that data scientists have become more valuable than ever. Indeed, their role in making businesses flourish is undoubtedly significant. However, since the pandemic started, they have also made a significant contribution in helping manage healthcare departments.

Since 2010, we have been growing our knowledge and capabilities in terms of algorithms, identifying patterns, and obtaining insights. However, since the pandemic hit us, the world of data science has seen abilities and potentials beyond what we ever imagined. Data scientists are now using their capabilities to help predict how the disease will affect various businesses and industries. So, is the pandemic opening a new door for data science? You might rightly think so.

Data scientists provide their skills and services for screening, analyzing, predicting, forecasting, tracing contacts, and developing drugs and solutions. If you think this is great, experts speculate that more of such services will come from the data science field very soon if the pandemic continues.

Experts speculate and hope that, soon, machine learning and data science will help categorize and predict which people are prone to getting the disease and which ones are immune and safe from Covid-19. Such categorization will be of immense help in many ways. It will help prioritize those who need the treatments and vaccinations first and who can wait. Plus, it will help reduce the spread of the disease and contain the damage.

Moreover, data science is also helping us keep track of Covid-19’s spread worldwide. Plus, we are also using data science at a macro level to assist what information and results disseminate and where. Such data and information help keep track of where the disease might spread next, where it can do the most damage, and how many waves we can expect.

Apart from these services, data science is also playing a vital role in making industries and businesses run. It’s helping companies make proper arrangements and decisions according to the data they receive and the information they structure out of it. This benefit applies to both private and government industries, and it’s helping many countries stabilize their economy and prevent them from collapsing.

Covid-19 Data Science Urban Epidemic Modelling And Visualization In Python

Since coronavirus spreads from person to person, to keep track of the virus among the population, you must keep track of the people. The disease goes where the people go. Understanding, analyzing, and predicting their movements can help us understand how the disease spreads, where it’ll spread to, and how to stop it effectively. Predicting where a disease virus is saturated and where it will move on to the next can help control the damage and minimize it.

Urban epidemic modeling and visualization in python is precisely this. Python is a coding language you will typically see in data science. Python is the most preferred, most popular programming language among data scientists worldwide. The reason for all this love for the language is how versatile it is. Data scientists use machine learning, special statistics, and complex networks to understand urban communities’ mobility.

Keeping track of the disease’s potential carriers can help you make proper predictions and appropriate measures to stop the disease’s spread. Data scientists use python to build epidemiological models while taking into account urban mobility patterns. Then, they convert the data into understandable, visually pleasing graphics and diagrams. This process includes simple mathematics, statistics, formulations, and special equations. Then, they present the information on a map so that it is easy to understand and interpret.

Online Data Science Courses During Covid-19 Crisis

With the rising demand for data scientists, more and more people are looking up to this profession and adopting it as a career. However, even those who are already certified need to take their game up a notch. The data world is transforming, and if you’re not up-to-date, you’ll soon be far behind the world and what it needs right now.
