The Comprehensive R Archive Network offers many data science packages, including popular libraries like tidy and ggplot2 within the tidyverse.

While the demand for R programmers is rising, there is a need for more proficient R data scientists compared to Python users. Consequently, R programmers command higher compensation, making R skills valuable in IT and data science.

3:      Statistics and Math Skills

Though optional to start learning data science, a strong foundation in mathematics and statistics is crucial for professional growth. Understanding statistics enables informed decision-making, proper data approach implementation, and a comprehensive grasp of the analyzed data.

Beyond standard curriculum mathematics, knowledge of calculus, probability, statistics, and linear algebra is recommended. Bayesian theory proficiency proves beneficial when working with AI and machine learning techniques.

4:      SQL Skills

Despite its inception in the 1960s, SQL remains an essential skill for data scientists. It serves as the gold standard for managing and communicating with relational databases.

Relational databases store vast amounts of structured data, making SQL proficiency vital for efficient data retrieval and analysis.

Unlike Python and R, SQL is a simple and fundamental programming language with wide industry usage. Data scientists should possess SQL knowledge due to its relevance in handling company data and relational database management.

5:      Data Visualization Skills

Data visualization plays a crucial role in conveying insights derived from data analysis. Effective communication of results to decision-makers and stakeholders is essential for driving action.

Data visualization presents information through graphs, charts, maps, and other graphical representations, simplifying complex data into easily understandable formats.

The field of data visualization continues to evolve, incorporating contributions from psychology and neuroscience. Various tools, including Python libraries and programs like Tableau and Power BI, aid data scientists in generating visually appealing and impactful representations.

6:      Machine Learning Skills

Machine learning is a prominent aspect of data science, focusing on developing algorithms that can autonomously acquire new skills.

Its applications permeate daily life, from personalized recommendations to social media filters. As the industry’s utilization of machine learning grows, data scientists proficient in this field are in high demand.

However, a significant gap exists between the demand and availability of skilled professionals. Companies increasingly rely on machine learning specialists, with 82% reporting a need, but only 12% believe an adequate supply exists.

7:      Natural Language Processing Skills

Natural Language Processing is a branch of AI that deals with understanding and deriving insights from unstructured text and speech. With the prevalence of language and written communication, NLP’s importance in the data sector continues to rise.

Applications such as search engines, chatbots, and recommendation systems utilize NLP approaches based on machine learning and deep learning.

Proficiency in NLP enables data scientists to extract valuable information from textual data and contribute to developing advanced language-driven technologies.

8:      Data Visualization

Data visualization is a crucial skill for data scientists, allowing them to present insights derived from data analysis effectively. Data visualization facilitates understanding and decision-making by transforming raw data into visually digestible formats like tables, charts, graphs, and maps.

Proficiency in visualization tools and techniques empowers data scientists to create compelling representations, both in Python and third-party programs such as Tableau.

Data science boot camps often include data visualization and presentation skills training, recognizing the importance of creating meaningful narratives with data.

9:      Cloud Computing

Data scientists need cloud computing to analyze and visualize cloud data. AWS, Azure, and Google Cloud certifications demonstrate proficiency with these products. Data scientists may use cloud computing to process, analyze, and store data efficiently.

·         AWS

AWS (Amazon Web Services) is a well-known cloud computing platform that offers services for the storing, processing, and analysis of data. The fact that its solutions can be scaled up at little cost is appealing to data scientists.

Integration and management of data-intensive projects may be carried out with the assistance of Amazon S3, Amazon EC2, and Amazon Redshift.
