A few years ago in data science, most job openings required a PhD or at least a master’s degree in mathematics, statistics, or a similar subject as a primary criterion. Everything has changed in the last couple of years. There has been widespread development of machine learning libraries that abstract away the complex nature of algorithms, as well as the realization that the practical application of machine learning to solve business problems requires a set of skills…

It’s easy to think that if you just knew the statistics better, data analysis wouldn’t be as difficult. It is true that more statistical knowledge is always useful. But I found that statistical knowledge is only part of the problem. Another key part is developing data analysis skills. These skills are applicable to all types of analysis. It doesn’t matter what statistical method or software you use. So even if you never need more statistical sophisticated analysis than a…

What is Data Science? In recent years the phrase “data science” has become a buzzword in the tech industry. The demand for data scientists has surged since the late 1990s, presenting new job opportunities and research areas for computer scientists. Before we delve into the computer science aspect of data science, it’s useful to know exactly what data science is and to explore the skills required to become a successful data scientist. Data science is…
