Organizations looking to make strategic decisions or drive innovation through data are bound to employ a highly qualified data scientist, but finding that perfect talent is not at all easy due to the blend of technical and soft skills entailed by the job. The important competencies that should exist in a data scientist will be briefly discussed, followed by some tips for the effective construction of the skill assessment, and a discussion about how to develop such competencies inside an already existing team concludes the article.

Top 6 Important Skills Required for Data Scientists
1. Mathematical and statistical analysis
Statistics and mathematics are the robust backbone of data science. Being articulate, a data scientist should analyze data for trends, variation, and the relationship between different variables involved. In-depth knowledge of regression, hypothesis testing, and probability theory, among other concepts, is critical in order to decipher useful insights from complex sets of data.
2. Programming skills
Python or R programming skills are hereby required for data manipulation, analysis, and machine learning. In fact, every good data scientist should not be afraid to write code either to automate some data processing routines or to implement an algorithm for predictive modelling.
3. Wrangling – data visualization
The key skills that a data scientist should possess include cleaning, processing, and visualizing the data. This could be further facilitated by familiarization with libraries such as Pandas and NumPy for processing the data and then using Matplotlib and Tableau for visualization. The objective is to take messy data and transform it into an understandable format for stakeholders who are going to take action based on the information.
4. Machine learning and AI
Understanding machine learning algorithms and frameworks is important since, very often, a data scientist builds and deploys models to solve certain business problems. Knowledge of supervised and unsupervised learning, together with experience in the usage of such platforms as TensorFlow or Scikit-learn, may distinguish an applicant.
5. Business acumen
A good data scientist should, above all, be aware of the business context. This refers to the ability to transform insight from data into an executable business strategy and to be able to effectively communicate with the non-technical stakeholders so that everyone is aligned and informed.
6. Teamwork and communication skills
Collaboration and communication will, therefore, be of essence, as data scientists are working closely with cross-functional teams. Clear presentation of findings and teamwork will go a long way in increasing the impact of the work done.

How to Develop The Data Science Skills of Your Employees?
Investing in the growth of existing employees can be just as strong an action as recruiting newcomers. Some effective approaches would be one or more of the following:
Training programs on offer
Provide training or workshop sessions in the basic enabling skills of data science, combined with working with capable instructors or online courses, which will greatly enhance employee knowledge and ability.
Hands-on projects encouraged
Provide employees with opportunities to work on real projects requiring data science skills. Practical applications will help them learn and increase their problem-solving capabilities.
Mentorship and peer learning
Encourage knowledge sharing under a culture of mentorship by having more experienced data scientists guide those who are less experienced through perhaps regular team meetings or study groups.
Access tools and resources
Keep your team abreast of the latest in data science through tools, software, and other resources. Subscriptions to relevant journals or online platforms may be provided for continuous learning.
Just so you know
With OnlineExamMaker quiz software, anyone can create & share professional online skills assessments easily.
Encourage participation in hackathons and competitions
