Before we share more info on this course, let’s do a deep dive into what the data science industry can offer you and what kind of preparation you would need to learn data science and establish a career.

What is data science?

Simply put, data science is the study of different sets of data and information that originate from different sources like markets or business environments. Data science involves the processing of large volumes of data to derive meaningful patterns and insights that can drive business decisions.

Although an actual data science cycle can be fairly complex, you can broadly divide it into 5 primary categories:

  • Capturing data: This stage involves data scientists gathering different structured or unstructured data.
  • Maintaining data: This step involves preparing the raw data in a way that makes it possible to process.
  • Processing data: This is one of the largest steps within the cycle and involves several data processing techniques such as data cleansing and data modelling.
  • Analysing data: This involves the further refinement of the processed data to derive significant statistical insights and information.
  • Communicating data insights: In the final step, the data insights are arranged into a simpler, more consumable format for business leaders and stakeholders.

What is a data scientist?

Data scientists are the professionals who are involved in one or more stages of a data science cycle. They use different data gathering, processing and analytical techniques to deliver important insights to business stakeholders.

As a data scientist, you get to use your expertise in arithmetics, statistics and data modelling to manage huge volumes of data and uncover business solutions.

What does a data scientist do?

Most data scientists work towards developing data-driven business solutions or insights which can improve company performance or revenue. However, the exact job role of a data scientist is company-specific and can differ from one organisation to another.

These are some common duties of a data scientist:

  • Designing different data collection campaigns and deciding the data entry criteria.
  • Building and designing data processing models.
  • Using different data visualisation techniques to process the data.
  • Arranging the data insights into usable reports and simplifying complex information for the benefit of stakeholders.

What are the benefits of opting for a career in data science?

Additionally, you can also look forward to the following career benefits if you choose to become a data scientist.

  • Handsome compensation packages: Owing to the enormous impact of data science in businesses, data scientists are some of the most well-paid workers in 2022. According to a report, an average data scientist in Germany can earn around € 55,461 per year.
  • Job security has created a growing demand for qualified data scientists: With each consecutive year, more and more businesses are warming up to the idea of utilising data science to grow their organisations. As a result, the demand for qualified data scientists is continuously growing. This trend can be expected to continue in the future, which can contribute to job security in the data science industry.
  • Immense diversity in the availability of data science positions: The ‘data scientist’ position is a blanket term for a large number of data science roles and jobs within the industry. You can choose any data science role in line with your career aspirations and professional strengths.
  • Possibility of working on innovative and novel projects due to constant evolutions in the field: The data science field is continuously growing because of innovations in AI and machine learning. This means that you will get to work on many innovative projects as a data scientist in the future.
