According to Forbes, by 2015 there was a need for 4.4 million data analysts worldwide. Robert Mitelstaedt, dean of the W. P. Carey School of Business in Arizona, said that companies have a high demand for data scientists “with a good mix of industrial engineering knowledge and command of supply chains for efficiency, cost savings and risk reduction” (Forbes, 2013). Additionally, Arizona State University reported that 85% of Fortune 500 companies with operations in the state have implemented big data initiatives, which has expanded the job market for data scientists.

In 2011, the McKinsey Global Institute reported that big data had “swept into every industry and business function and are now an important factor of production, alongside labor and capital.” According to the report, the computer and electronic products and information sectors, finance and insurance, and government are the sectors benefitting most from the use of data science.
Data scientists in Arizona have the opportunity to work for technology staffing firms like Robert Half Technology in Peoria, which contracts data scientists to work with IT and other technology clients to design experiments, test hypotheses, and build models. Arizona’s data scientists are also found working with companies like Carvana, an online car market headquartered in Phoenix that hires data scientists to develop insights and isolate new marketing strategies based on datasets gained from used vehicle inspection and certification processes.
Preparing for a Master’s Degree in Data Science in Arizona
Bachelor’s-prepared professionals seeking a master’s degree in data science are expected to meet a variety of qualifications in related to past education, related employment experience and key proficiencies. Master’s programs have highly selective standards and require candidates to possess a diverse skill set, prerequisite courses, high scores on graduate entrance exams, and employment experience.
Undergraduate Degree and Master’s Prerequisite Courses
Applicants to data science master’s programs must meet several minimum qualifications in order to be considered. These often include:
- Bachelor’s degree in a related field such as statistics, computer science, engineering, or applied math
- Minimum of 3.0 GPA during undergraduate studies
Applicants are also expected to complete prerequisite courses before enrolling in the program. Required prerequisites usually include:
- Calculus I & II
- Linear algebra
Master’s program applicants are generally expected to demonstrate a knowledge of fundamental quantitative concepts, score in the 85th percentile on either the GRE or GMAT exam, and have at least 5-7 years of related work experience.
Data science courses build off of certain fundamental concepts that enrolling students are expected to be familiar with, including:
- Data structures
- Algorithms and analysis of algorithms
- Linear algebra
Preparing for Success on the GRE/GMAT Exams
In order to be considered for admission, master’s program applicants are typically expected to score in the top 15 percent on the quantitative section of the GRE or GMAT. In addition, admission departments place a particular emphasis on excellent verbal and writing scores, as data science professionals are expected to possess strong communication skills.
The GRE exam’s quantitative section evaluates the candidate’s abilities in data analysis, arithmetic, algebra, and geometry. Topics especially relevant to data scientists include statistics, standard deviation, tables, graphs, and probabilities. The official GRE website offers sample questions and free practice exams.
The General Management Admissions Test (GMAT) also evaluates student’s quantitative skills and familiarity with data analysis. With 37 questions involving problem solving and data efficiency, admissions departments expect an excellent quantitative score as well as high verbal and writing scores. GMAT practice exams are available through The Princeton Review and Veritas Prep.
Prior Work Experience
Admissions departments for data science master’s programs seek bachelor’s-prepared professionals who have 5-7 years of experience in data science or a related field. The following skills are generally expected of master’s program applicants:
- Strong communication skills
- Programming proficiency in languages such as JAVA, C++, and Python
- Coding skills
- Hacking skills
- Data mining ability
- Database administration proficiency
A few examples of the kinds of employers and entry-level positions that would satisfy work experience requirements for a master’s program in data science might include:
Entry Level Data Analyst at ConsultNet in Phoenix – Data Analyst works with a team to review suspicious banking transactions, analyze the trends in transaction history, and write up narratives for company executives to forward to cooperating banking institutions.
Data Engineer at American Express in Phoenix – Data engineer will create data structures and databases, build and enhance the database structure, work with database analysts, administrators, and architects, and facilitate improvements across all company levels by presenting pertinent information to management.
Clinical Data Analyst at Statistics & Data Corporation in Temple – Clinical data analyst will perform data entry, query management, and review of datasets, as well as assisting in database setup and maintaining quality control of the data as part of a larger data science team.
Bridge Programs and Massive Open Online Course (MOOC) Options for Master’s Programs Applicants Who Do Not Meet Admission Criteria
Applicants to data science master’s programs are expected to possess a diverse array of qualifications. Master’s courses build on an established knowledge of mathematics and programming languages. Some applicants may not meet each requirement and choose to enroll in bridge programs or massive online open courses (MOOCs) to fill the gaps in their education or experience.
Bridge programs are offered through schools that house data science programs as a way for students that meet all other enrollment criteria to fill knowledge gaps before beginning graduate level coursework. Bridge programs are generally offered in one of two areas:
- Fundamental bridge programs, including courses in linear algebra, algorithms and analysis of algorithms, and data structures
- Programming bridge programs, including essential programming languages such as Python, JAVA, and C++
MOOCs are online-hosted educational programs offered completely independent of graduate programs. MOOCs are designed to fill knowledge gaps before enrolling in a master’s program. They include problem modules, filmed lectures, and the opportunity to interact with professors and teaching assistants. There are many different online hosts for prospective data science graduate students that wish to fill gaps in their knowledge prior to enrolling in a master’s program.
