Our 2016 report, Growth of the Bootcamp Model highlights growth in the field of data science and the steadily increasing number of programs churning out data scientists to fill the market gap. When it comes to this industry, there are a lot of terms thrown around—Data Science, Data Engineering, Data Analytics, bootcamps, and fellowships. The job titles are even more varied! With the help of NYC Data Science Academy, this guide will help you make sense of data science, the technologies and frameworks data scientists use and the types of jobs available in the industry.

What is Data Science?

According to NYC Data Science Academy, Data science is a multi-disciplinary field that combines computer science and statistics. The objective of data science is to pull insightful and useful knowledge out of datasets which, at times, can be too large for traditional statistics to analyze. This can include anything from analyzing complex genomic structures, to interpreting handwriting, to optimizing a marketing strategy.

Data Science Director, Josh Wills offers this definition of Data Scientists, a “person who is better at statistics than any software engineer and better at software engineering than any statistician.” Most data science bootcamps require an aptitude for math and statistics, and in some cases knowledge of a programming language, such as R or Python.

Data Science vs. Data Engineering vs. Data Analytics

Data Science bootcamp or Data Analytics bootcamp, what’s the difference? NYC Data Science Academy offers some insight into the different branches of Data Science and the technologies used in each field:

Data Science is a cross-disciplinary field requiring skills in Computer Science (Machine learning), Statistics and Mathematics. Typically, it requires candidates to have an advanced degree in a STEM field (e.g., Science, Technology, Engineering, Mathematics, Statistics) and a good understanding of the sophisticated concepts underlying modeling. Most Data Scientists use R and/or Python as their primary tools.

Data Engineering leans more towards software engineering and computer science, with just some knowledge of data science. It mainly covers Hadoop, Spark, Python, Java and Scala. It entails writing scripts and being familiar with tools to input and extract data from big data warehouses.

Data Analytics is considered more entry-level and focuses on BI (business intelligence). Its focus is to draw business insights from commonly seen data types. It includes data cleaning, data visualization and simple modeling including linear regression. Common Data Analytics tools are SQL and Excel.

Data Science Bootcamps vs. Data Science Fellowships

There are significant differences between data science bootcamps and fellowships. Data Science bootcamps prepare individuals with some knowledge, but limited experience for roles as data scientists in intensive 3-6 month programs. For most bootcamps, a bachelor's degree and math aptitude are required. However, some schools, such as NYC Data Science Academy, require students to have a masters or Ph.D. The bootcamp tuition ranges from $6,500 to $21,000. 

Unlike Data Science bootcamps, Data Science fellowships are generally free to the student (revenue is generated through hiring partnerships). Data Science fellowships generally require more experience than bootcamps. For example, the Data Incubator requires candidates to have a Masters degree or Ph.D. in a social science or engineering field and relevant work experience. Data Science fellowships help academic data scientists prepare for work in a corporation or startup. According to a white paper by Insight Data Science, there are “400 Insight Fellows working as data scientists and engineers across the United States.”

What is “big data”?

Many Data Science courses use the term Big Data to describe their curriculum content. What exactly is “big data”? NYC Data Science Academy tells us below.

“Big data” is a term coined to describe datasets that are too large to be analyzed on one computer. With the advent of the internet, streaming data, wearables, etc, the amount of data being produced each day equals all the data ever created up to the year 2003. This data holds insights that can be useful for decision makers, but its sheer volume, together with the usual problems of corruption, incompatibility, and complex structure (often including natural language), make it challenging to use. Sophisticated tools (e.g, Hadoop, Spark) that can employ multiple computers simultaneously are required to extract actionable knowledge from this data.  

Data Science Technologies

The technologies learned at a Data Science bootcamp often differ from what is taught at a traditional coding bootcamp. Here, NYC Data Science Academy breaks down common technologies used in the field and what they’re used for.

What kind of background should data scientists have?

While having math aptitude is important, Data Scientists come from a variety of educational and professional backgrounds. Check out some of our Q&A’s with Data Science bootcamp grads:

Data Science Jobs

As with most fields, Data Science job titles don’t always give you the nuts and bolts of what the job entails. Below are some common job titles you’ll come across when looking for jobs in data science and their average salaries.

Data Analyst

Data Analysts are responsible for analyzing large datasets whether for customer research, business intelligence or internal studies. Data Analysts start with a large data set and are tasked with drawing actionable conclusions from this data. Data Analysts may work with engineers, UX Researchers and Sales staff to develop growth solutions. In addition to data science tools like SQL, Data Analysts should also have knowledge of statistics and concepts like A/B testing.

Average Salary - $62,000

Data Scientist

Data Scientists are responsible for determining the data necessary to answer a question, from designing a method for capturing data to gathering data, analyzing data and finally presenting the solution. Similar to the Data Analyst, the Data Scientist’s role is much larger in scope and requires careful planning and design of research from beginning to end. Data Scientists will use the full gamut of data science tools including as Python, MongoDB, Hadoop and more.

Average Salary - $117,000

Data Scientist - Core Digital Media

Database Administrator

Database Administrators work with technologies such as MySQL, MongoDB, and Postgres to manage large datasets. Depending on the company and role, their duties may include investigating and solving database problems, repairing glitches and designing elements that improve the storage and maintenance of data.

Average Salary - $69,000

Database Administrator - Squarespace

Data engineer

Data Engineers are half software developer, half data scientist. Data Engineers use programming languages to write scripts that capture data. Data Engineers then analyze the data and make program or product recommendations based on their analyses.

Average Salary - $104,000

Data Engineer - Factual
