When you hear the term data science, do you think spreadsheets, numbers, and mad scientists? Data science helps us understand all of the data that we’re collecting, and helps turn that data into action. The field is in high-demand – 2.7 million jobs will need to be filled by 2020! In this data-drive culture, companies now more than ever require data analysis skills to enhance business growth. And to fill the market gap, data science bootcamps are steadily growing, training thousands of data scientists each year. Read on for a crash course in data science and our picks for the best data science bootcamps.

What is Data Science?

Data science is a multidisciplinary 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. NYC Data Science Academy. Director, Josh Wills, says that a data scientist is a “person who is better at statistics than any software engineer and better at software engineering than any statistician.”

The Data Science Job Market

According to IBM, by 2020, the data analysis workforce will grow by 28% and the number of roles will increase from 364,000 to 2.7 million. For data science and other advanced data roles, the demand will reach 61,800. The democratization of data has governments, businesses, and organizations measuring any and everything to make better business decisions.

What’s the average salary for a Data Scientist?

The average salary for Data Science Analysts is $80,265, while the average salary for advanced Data Scientists and Data Engineers is $105,909.

Data Science vs. Data Engineering vs. Data Analytics

You’ve probably heard these terms – Data Science, Data Engineering, and Data Analytics – here are the differences:

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 data science fellowships. Data science bootcamps are geared towards students with a bachelor's degree and an aptitude for math and statistics (no PhD required, but it helps to know a programming language like R or Python). Some schools, such as NYC Data Science Academy, and Science 2 Data Science require students to have a PhD or masters. Data science bootcamps are intensive 3-6 month programs and prepare graduates for entry-level and junior data science jobs.

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, fellowships are a great bridge between academia and a career. The program enables data professionals to learn the industry-specific skills needed to succeed in the growing field.

What is “big data”?

Many data science courses use the term “big data” to describe their curriculum content. But what exactly is “big data”?

According to NYC Data Science Academy, “big data” is a term coined to describe data sets 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.  

Most Common Data Science Technologies

The technologies learned at a data science bootcamp often differ from what is taught at a traditional coding bootcamp. Let’s break down the 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. Common background skills include: problem-solving, logical reasoning, communication, and being detail-oriented. For a better idea of the types of students who are successful, check out these Q&As:

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 - $64,425

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 - $131,836

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 - $84,641

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 - $127,624
