If you’re here, the question you’ve probably asked yourself is: “Why should I choose a data science course for a bright career?”
The answer is simple: data science is a much-sought-after career, and there are plenty of companies looking to hire data scientists. Data science is the most growing field where new job opportunities are popping up every day.
In fact, according to the Bureau of Labor Statistics (BLS), demand for data scientists will grow by more than 40% between 2022 and 2028! Plus, with all this growth, there will be more competition for those jobs than ever before.
So what does all this mean?
It means that in order for you to get hired as a data scientist, you need to have some skills that are both in demand and essential for the job.
Data Science course is a new course being offered by major universities and certification organisations. Data Science can be studied as a standalone programme or as part of a larger programme such as Machine Learning, Artificial Intelligence, Data Analytics, or Big Data.
All of the concepts you see in Hollywood science fiction films could become a reality thanks to data science courses. Data Science is the future of artificial intelligence. As a result, it is critical to understand what Data Science is and how it can benefit your business.

What is Data Science
Data science is technological job career. It is a study that deals with the analysis of huge volumes of data using state-of-the-art tools and methods to find patterns, crucial details, and insights that support smart decision making.
As a result, Data Science is primarily used to make decisions and predictions using predictive causal analytics, prescriptive analytics (predictive and decision science), and machine learning.
Predictive causal analytics: Predictive causal analytics is required if you want a model that can predict the possibility of a specific event in the future.
If you lend money to someone on credit, for instance, you might be concerned about their ability to make their credit payments on time in the future.
Here, you can create a model that can perform predictive analytics on the customer’s payment history to predict whether or not future payments will be made on time.
Prescriptive analytics: Prescriptive analytics are required if you want a model with the intelligence to make its own decisions and the ability to modify it with dynamic parameters.
This relatively new profession is all about giving advice. In other words, it not only predicts but also suggests a set of prescribed actions and outcomes.
The best example is Google’s self-driving car, which I also discussed earlier. Vehicle data can be used to train self-driving vehicles.
On this data, you can run algorithms to give it intelligence. This will allow your car to make decisions such as when to turn, which path to take, and when to slow down or accelerate.
Machine learning for predictions: If you have financial company transactional data and need to build a model to predict future trends, machine learning algorithms are your best bet. This falls under the supervised learning paradigm.
When you train your machines using data that you already have, this is referred to as “supervised” machine learning. An example of this is the training of a fraud detection model using past data on fraudulent purchases.
Machine Learning for Pattern Discovery: If you don’t have the parameters from which to make predictions, you must discover hidden patterns within the dataset to make meaningful predictions.
Since there are no predefined labels for grouping, this is an unsupervised model. Clustering is the most commonly used pattern discovery algorithm.
Assume you work for a telephone company and need to build a network by placing towers throughout a region. Then, using the clustering technique, you can find tower locations that will ensure that all users receive optimal signal strength.
Who are Data Scientists and what does a data scientist do?
For Data Scientists, there are several definitions available. A Data Scientist is someone who practises the art of data science. The term “Data Scientist” was coined in response to the fact that a Data Scientist draws a significant amount of information from scientific fields and applications, whether statistics or mathematics.
Data scientists are those who use their expertise in specific scientific disciplines to solve complex data problems. They work with a variety of mathematical, statistical, and computer science elements (though they may not be an expert in all these fields).
They make extensive use of cutting-edge technology to solve problems and reach critical conclusions for an organisation’s growth and development.
Skills required in data science according to coursera
Coursera is provides online courses and new career options. According to them Data Science is the most demanded career path, you should choose.
In a field like data science, there are a number of technical skills that are helpful to have before diving in, such as:
- Deep knowledge and familiarity with statistical analysis
- Machine learning
- Deep learning
- Data visualization
- Mathematics
- Programming
- Ability to manage unstructured data
- Familiarity with SAS, Hadoop, Spark, Python, R, and other data analysis tools
