Is Data Science a Good Major?

Data science is usually an interdisciplinary major.  It’s typically necessary for data science students to take courses in multiple academic departments:

  • Computer science
  • Mathematics
  • Statistics
  • Machine learning
  • Business

Depending on how a student’s college is organized, this can sometimes make for a challenging and disjointed experience. It’s ideal to seek out a data science degree program where there is a close collaboration between the relevant departments, particularly the areas of:

  • math
  • statistics
  • computer science
  • machine learning

To master data science is to master the areas that make up the field.  This collaboration can help to cut down on some of the inherent difficulties with a data science major.

Is it a hard major?  Some students might enjoy the variety of course requirements and thrive in a major that requires such intensive learning. Others will find it too difficult to mentally “switch gears” between all these disciplines. It’s can also be problematic when data science aspirants fail to grasp the intricate relationships between these disciplines; it’s necessary for students to connect them all seamlessly.

What are the Typical Course Requirements for a Data Science Major?

A data science major is typically comprised of a combination of courses.  We take a look at some of the most common courses required as part of a data science major.

Mathematics and Statistics Courses

Popular courses include:

  • calculus
  • multivariate calculus
  • analytic geometry
  • linear algebra
  • discrete mathematics
  • statistical methods
  • probability

Computer Science and Machine Learning Courses

  • data structures
  • data analytics
  • data visualization
  • deep learning
  • data mining
  • regression analysis
  • predictive analytics
  • algorithms and software engineering
  • object-oriented programming
  • introduction to artificial intelligence
  • database systems
  • a variety of programming languages and Big Data tools

Other Foundation Courses

Many data science degree programs require some other basic foundational courses like ethics, writing, and an introductory science course.

A Capstone Project

Many data science degree programs require students to complete a final data science project, known as a “capstone project”, under the supervision of an academic advisor.

Data literacy resulting from the completion of these types of courses could be helpful to an individual seeking a career in data science in almost any industry, according to Wired.

Is data science hard?  Whether a student would find these data science major course requirements hard or not is largely a matter of individual opinion. The rigorousness of each class can also depend a great deal on the professors who are teaching.

Solving Problems Versus Writing Papers

Solving Problems Versus Writing PapersA data science degree requires students to spend significant amounts of time troubleshooting code and solving problems. This is a major that doesn’t require the intensive volume of paper writing that many other major courses of study require. This could be an advantage for students who hate writing papers and find it difficult. Conversely, verbally gifted students who want to spend their academic lives writing papers could find data science to be a hard major.

Data science degrees also require more hands-on learning than some other majors. It’s not as simple as attending class and getting questions right. Data science students need to prove their knowledge and skills in actual business settings. Most data science schools have corporate partners for internship placements. Popular data science internship sites include:

  • Intel
  • LinkedIn
  • Cisco
  • McKinsey
  • Boeing
  • Intuit

Internships put students into a data scientist’s shoes and real-life projects. Supervisors expect interns to already have hard skills like C++ and SQL. Students who lack tech prowess and hate math will struggle in data science internships.

Is Data Science Harder Than Computer Science? 

Data science and computer science have similar characteristics and require a similar skill set, but there are differences.  They both use computer languages like Java or Python but for different reasons.  A data scientist would use them to analyze different metrics.  A computer scientist would be interested in how the languages operate.  Computer science programs provide students with a wide base of knowledge around computing while data science programs would focus more on analysis.  One is not necessarily harder than the other, but they are different.

What are the Different Types of Data Science Degrees?

Is becoming a data scientist hard?  The answer to this usually depends on the degree level. Data science courses get increasingly difficult each year. Introductory 100-level data science courses could be a piece of cake. However, 300- and 400-level courses in the junior or senior year will be tough stuff. Graduate courses in data science are unsurprisingly the most challenging. The highest level of 900-level classes will require extensive technical abilities to mine data sets.

One way to check a data science program’s difficulty level is to review the graduation rate. The National Center for Education Statistics tracks graduation rates. Programs with high graduation rates over 90 percent are likely less trying. Low graduation rates suggest fewer students make it through because it’s harder. There’s a potential caveat though. Schools with already low acceptance rates only admit top-notch students ready to tackle the curriculum. Here’s what to expect at each data science degree level.

Bachelor of Science in Data Science

Earning a bachelor’s degree isn’t an easy feat, but it’s the least specialized degree level. Bachelor’s degrees require 120-130 credits total. Of those credits, about one-third will be in data science subjects. Undergraduate schools have a general education curriculum that covers diverse basic courses from English to history.

The best major for data science students is, of course, data science but several other majors are popular choices including computer science and information technologies.  While data science is a technical degree, non-technical courses are a huge slice of the curriculum. Bachelor’s majors could even fill their electives with simple classes like PE. Ambitious students can choose extremely hard electives, such as Financial Engineering. Bachelor’s degrees are as hard as aspiring data scientists make them.

Master of Science in Data Science

Completing an M.S. in Data Science is inherently harder than the undergrad major. Master’s degrees are meant to push students forward with more technical, specialized courses. For unrelated majors like art or philosophy, the Master of Science will be an extreme change. For data science graduates, the transition won’t be as dreadful. Data science majors already have prerequisite courses for a shorter study time too.

A master’s curricula generally requires 30 to 48 credits beyond the 400 level. The program may offer complex concentrations including:

  • Artificial Intelligence
  • Data Engineering
  • Health Analytics

Whether online or on-campus, master’s courses lead to a thesis project. Taking on a graduate assistantship would add 10-20 hours more work weekly.

Doctor of Philosophy in Data Science

Finishing a Ph.D. in Data Science is a tremendous accomplishment. On a difficulty scale of 1-10, doctorates are an 11. The Doctor of Philosophy is an intensive, research-based program reserved for scholars in the upper echelon of the field. Most successful Ph.D. candidates have superior GPAs and Graduate Record Exam scores. After all, doctoral degrees usually only admit 5-10 people each year. Above-average understanding of statistics and coding is crucial to compete.

Once admitted, candidates are paired 1:1 with doctoral advisors to get through complicated seminars. Doctoral curricula leads up to an in-depth dissertation project. Students need to complete original research, write a paper of 100-200 pages, and give a dissertation defense.
