In an effort to increase diversity, the school encourages women, minorities and individuals with disabilities to apply. Each student receives a $5,000 stipend and a laptop.
The intensive, 7-week fellowship touts itself as the bridge to a career in data engineering. It takes place in New York City and Silicon Valley and is open to anyone with a strong background in math, computer science and software engineering fundamentals. They also seek fellows who come from positions in the industry or directly from degree programs (bachelor’s, master’s and PhD). In the program, students will be able to participate in project-based learning and work with top industry mentors.
Comparison of data analyst, data scientist, and data engineering roles
A data analyst role can be found at pretty much any large corporation or government organization. From accounting, to risk analysis, to a/b testing, to working on government data, there are a lot of data analyst roles out there. A data analyst is basically a junior data scientist. It’s a good place to start if you don’t have a very technical background and have only taken one or two statistics classes.
You won’t be required to have mathematical background or a PhD/research experience, but you will be required to be diligent, strong at communication, and able to perform computer work. Once you get more experience as a data analyst, you can take more advanced courses, earn a master’s degree or consider a data-science bootcamp to jump into a more research-based, analytical role.
Data analysts need to have some basic understanding of the following subjects: Excel spreadsheet, basic statistics (college-level intro classes), basic statistical tools (like STATA/SPSS), producing graphs and diagrams and presenting simple summary results.
A strong attention to detail is necessary as processing data requires much diligence, patience and an eye for error. You'll be manipulating small to large datasets, and it's very easy to make mistakes.
Day-to-day You'll be given specific instruction from a more senior member and will likely be using Excel to process data and produce summary results. Things like bar charts, pie charts, trend lines, simple regression analysis, box plots, etc., will be common day-to-day tasks. As a side note: You may also be querying databases for data using SQL and scripting languages. For this reason, it is not a bad idea to learn some basic SQL programming. It's important to remember that you won't be doing complicated analysis independently or building your own statistical models or any type of predictive analysis. These higher level tasks are usually conducted by data scientists or senior researchers.
Some companies treat the titles of “data scientist” and “data analyst” as the same thing and they are often used interchangeably. However, in general, there are some distinctions between the two. A data scientist’s work usually needs more complicated analysis and a stronger understanding of the fundamentals of statistics. A strong background in college and graduate level statistics coursework is needed for a career as a data scientist. Usually job listings will require a master’s degree in quantitative finance, statistics, or some relevant field.
While a data analyst simply may be doing work in excel to present summary statistics of small datasets, a data scientist will be managing larger data sets from different sources. They'll likely be comfortable with Python and R programming and using advanced statistical models and tools like STATA and SPSS. SQL and basic scripting languages are a must-know for data scientists
Data scientists are often employed by technology and financial sectors, where huge volumes of data are being processed every day. As new data comes in and new problems come up, these data scientists are employed to find ways to optimize a company’s marketing campaign, optimize a hedge fund’s trading algorithm, or come up with new ways to predict or model consumer behavior. The end goal is to make full use of the company’s data to help generate profits and make the products better.
Note that in different industries, often times they require specialized knowledge. For example, in the medical industry they require knowledge of biostatistics and bio-statistical models, which can be different to financial statistics and financial modeling.
A data engineer is very different to a data scientist. Think of a data engineer as more of a computer scientist who specializes in building systems to manage data. They focus on creating robust data systems that can aggregate, process, clean, transform, and store large amounts of data. Typically in large corporations a data engineer builds a robust, fault-tolerant data pipeline that cleans, transforms, and aggregates unorganized and messy data into databases or datasources. Data engineers are typically software engineers by trade. Instead of data analysis, data engineers are responsible for compiling and installing database systems, writing complex queries, scaling to multiple machines, and putting disaster recovery systems into place.
Data engineers essentially lay the groundwork for a data analyst or data scientist to easily retrieve the needed data for their evaluations and experiments.
Skills and tools: Data engineers need to have strong knowledge of core computer science principles and software development experience. In addition, they need to have expertise in new technologies that help manage large datasets. These technologies and concepts include MapReduce, NoSQL databases, MongoDB, SQL, Hadoop, Storm, and other various Dev Ops tools like Chef. You will need the ability to learn whatever technology the company is using to manage their data systems, and there are a wide variety of them, although the core underlying principles are very similar.
The McKinsey Global Institute has predicted that by 2018 the U.S. could face a shortage of between 140,000 to 190,000 people with deep analytical skills, and a shortage of 1.5 million managers and analysts who know how to leverage data analysis to make effective decisions.
With that in mind, there a going to be a lot of job opportunities opening up for people with the right skill set. As a results a lot of new education programs have popped up to fill that need and gap. However, being a highly-specialized profession, transitioning into a data science career will require not just basic training, but lots of specialized coursework and experience.
