Their capacity to bridge the gap between data analysis and business objectives makes them invaluable assets in today’s data-driven business landscape. 

The education required to become a data scientist usually requires a complex academic background that involves skills such as a Ph.D. Some of the basic education qualifications that are needed are a Master’s degree in statistics, computer science, or engineering. In terms of technical skills, it is presumed that the candidates should be competent or highly proficient in programming with proficiency in one or more software languages, especially Python, statistical analysis, machine learning, Data Visualization, and Mathematics. Moreover, hard skills such as business sense/awareness, interpersonal communication, ability to analyze data and draw accurate insights, logical approach/problem-solving, decision-making, and creativity are also important precursors to the profession.

Data scientists, including Python, table, SQL, JavaScript, Scala, and C/C++, employ several languages. The purpose of these languages varies and includes data analysis, data visualization, machine learning, and databases. It uses languages that are popular and relatively easy to learn, and there are plenty of available libraries and tools to support data science. However, data scientists might use tools/technology stacks such as Apache Spark, Matlab, SAS Anaconda, etc, to boost their efficiency in terms of these languages.

The primary task of data scientists is to apply linear algebra and statistical techniques to train logistic regression models on specified inputs and produce valid outputs. Examples of the standard algorithms embraced include linear regression for predictive analysis, logistic regression analysis for classification, neural network for intricate pattern analysis, and gradient boost for better estimates of the result. These are algorithms that are trained to make decisions and provide solutions in particular businesses without always requiring human input.

In a typical day of work, one gets to go through the data science cycle, which is data acquisition and preprocessing, data exploration to understand the data, creating and training models, and assessing the models’ performance while presenting the results to the appropriate audiences. It is essential to know that this workflow is generally not a linear process where a data scientist fully completes one step before moving to the next. Still, often, the process requires going back and forth between steps to improve the analysis and its models.

This paper identified some of the common obstacles to data scientists, namely data availability and accessibility, data quality, dealing with a big data set, data security, and result interpretation for a non-technical audience. The difficulties are usually associated with the specified field and more often require technical, practical, and analytical approaches to address them.
