What are the key skills of a Data Scientist?

While it is possible for just anyone to build expertise in Data Science, the question is how to do so.  

If you aspire to become a Data Scientist, you must have certain technical as well as non-technical skill-sets. These skill-sets are prerequisites to building a career in this revolutionary technology and will help in career growth. 

4 ReasonsMust have technical skill sets for an aspiring Data Scientist

Mathematics and statistics: As a Data Scientist, you will use capital processes, algorithms or systems to get valuable insights and make informed decisions from data. Here good knowledge of mathematics and statistics would help you while making estimation for further analysis. If you wish to build a career in Data Science, you should be familiar with the following topics of 

  • Derivatives and gradients
  • Step function, Sigmoid function, Logit function
  • Cost function
  • Plotting of functions
  • Minimum and Maximum values of a function
  • Scalar, vector, matrix and tensor functions

Programming languages: Programming languages are a crucial part of Data Science, they are essential in transforming raw data into actionable insights. While you can select any programming language of your choice, Python is the most in-demand. The other programming languages that you can select from are Python, R, SQL, Spark, Hadoop, Java, Tableau, AWS, SAS, Hive, Scala, C++, Excel and Azure. 

Data Wrangling: While dealing with massive amounts of data, it is important to understand and know how to deal with its imperfections. To do so you should prepare your data for further analysis, which can be done through Data Wrangling. Good knowledge of this would help you gain deep intelligence within your data by gathering data from multiple channels. 

Data Visualization: Data Visualization refers to the graphical representation of the findings from the data. It effectively communicates and leads the exploration to the conclusion. You can use a number of visualization processes such as Histograms, Bar charts, Pie charts, Scatter plots, Line plots, Time series, Relationship maps, Heat maps, Geo Maps, 3-D Plots, and others for effective Data Visualization. 

Machine Learning and Deep Learning: A good knowledge of Machine Learning is required when the decision-making process is data-centric. As a subset of the Data Science ecosystem, Machine Learning contributes to the modeling of data and obtaining results. Machine Learning for Data Science includes algorithms such as K-nearest neighbours, Random Forests, Naive Bayes, and Regression Models.

Apart from the technical knowledge, there are some non-technical skills that a person must have to become a successful Data Scientist:

  • Analytical mindset: As a Data Scientist, your primary job will be the analysis of data. Having an analytical mindset would help you to a great extent. 
  • Creative problem-solving skills: For every individual, problem-solving skill is a crucial skill to have. While it helps in every step of your life it is especially required when you aspire to build a career in Data Science. A person who is creative while solving a problem is greatly valued by employers.
  • Business thinking: Business thinking is an essential knowledge a Data Scientist should have. This will help you to continuously provide value through the provision of insights that can be acted upon.
  • As Data Science is mainly about data, you must be curious about the data that you will be dealing with. And you should think practical. It will help you make informed decisions. 

How to build a career in Data Science?

One needs to have the knowledge of mathematics, statistics and programming as a data scientist. Since most roles in Data Science bridge IT and management, you can experience both the domains and plan your career moves swiftly.

To build your expertise you can take up online certification courses that are specifically designed for aspiring Data Scientists. The carefully curated course modules of such programs will help you develop these skills and will help you land a job in Data Science. Those who aspire to build a career in Data Science should have all the required expertise and should be open for consistent and continuous learning. There are programs which are specifically designed for freshers and young IT professionals seeking Data Scientist roles. 

Data Science is going to be a game-changer not only for the industry but also for your career.
