Program Questions

Who should apply?

Students who are an ideal fit for the MADS program desire a career in a fast-paced, high-growth industry in the United States immediately following graduation. MADS graduates have successfully gained positions as data scientists, data analysts, and data engineers in diverse industries such as banking, sports, health care, government, and tech. 

There are a variety of programs at CMU for students who are interested in related specific statistical graduate study topics and related outcomes. The Master of Science in Computational Finance (MSCF) is a program for students specifically interested in quantitative finance, and the Master of Science in Machine Learning is a program for students specifically interested in advanced study in machine learning.

Do I need to have a degree in statistics to be considered for MADS?

We welcome all majors yet we ask that students demonstrate academic success in the prerequisite courses in order to maximize success in the program. Please see the prerequisites at right.

What are the prerequisites for the program?

The program is highly rigorous and intense. We want our students to be set up for success in the classroom. At the time of applying to the MADS program, successful applicants are highly encouraged to have: 

  • Two semesters of calculus-based probability and mathematical statistics (CMU prerequisite classes are 36-225 and 36-226)

    Topics should include: random variables, distribution functions, joint and conditional distributions, functions of random variables & their probability distributions; maximum likelihood estimation, properties of estimators, hypothesis testing, interval estimation.

    Typical Textbook: Mathematical Statistics with Applications - Wackerly, et al. or equivalent
    CMU classes are: 36-225 and 36-226
  • One course in linear regression analysis (a CMU prerequisite course is 36-401)

    Topics should include: exploratory data analysis, linear regression models, validation and interpretation of models

    Typical Textbook: Applied Linear Regression Models - Kutner, et al. or equivalent. A good Econometrics course is an acceptable substitute.
  • Familiarity/exposure with matrix algebra and/or linear algebra. Applicants should be familiar with vectors and matrices, matrix multiplication, and inverses.

Can I take classes outside of the Department of Statistics & Data Science?

MADS students are typically not permitted to take courses outside of the Department of Statistics & Data Science. Normally, all the MADS students take core requirements together as a cohort. Electives are offered on a rotating basis.

Alternative courses within the Department of Statistics & Data Science may be allowed as a substitute should a comparable course of study already have been successfully completed prior to entry into the MADS program — any substitutions are considered on a case-by-case basis and must be approved by the Department of Statistics & Data Science.

Admissions Questions

How much is the application fee?

If you apply by November 3, 2024, the application fee is $50.00.  After November 4, 2024, the program application fee is $75.00.  We will accept applications thereafter on a rolling basis after the regular deadline as long as space remains in the incoming class but recommend applications are submitted prior to the cycle deadline to ensure an application review.

All application fees are paid at the time of application submission. The online application system accepts payments via credit card only. Please be advised that we do not accept cash or checks. For additional questions, please contact MADS-admissions@stat.cmu.edu.

What is considered a complete application?

A completed application must include:

  • Application fee
  • Undergraduate and graduate transcripts of all institutions where you have attended and/or graduated
  • Applicant background, goals and post-graduation objectives
  • A resume
  • Three recommendation letters uploaded by recommenders (two of which should be faculty recommendations)
  • If applicable, GRE General Test scores. Our GRE codes are 2074 (Institution) and 0705 (Department).
  • If applicable, TOEFL, IELTS test, or Duolingo scores. Our TOEFL codes are 2074 (Institution) and 59 (Department) 

Will you review my application if it is incomplete?

To ensure an equitable process for all applicants, we will review only all fully completed applications submitted by January 15, 2025, and only additional fully completed applications submitted after January 15 if there is space available in the program.

A hallmark of the MADS program is a small cohort size to facilitate a high-touch student experience.

What is the recommended TOEFL score?

All non-native English speakers are required to submit valid, non-expired TOEFL scores. A desirable total TOEFL score is 105 or higher. Speaking TOEFL scores should be at least 26. IELTS is also acceptable, with a desirable speaking score of at least 9.

What if I cannot take the TOEFL or IELTS?

We understand that in some cases it may not be possible for an applicant to test for TOEFL or IELTS. If you are not a native English speaker, and despite your best efforts are unable to test for TOEFL or IELTS, we will accept the Duolingo English proficiency test. A score of at least 135 overall is desirable.  We will give consideration to those with the following subscores and above:

  • Literacy: 135
  • Conversation: 130
  • Comprehension: 145
  • Production: 113

All scores must be uploaded and received before the deadline in order to assure an equitable review of your application.

How long are TOEFL scores valid?

If you need to retake your TOEFL, IELTS and/or GRE for this application, we highly recommend you take the exam no later than November 29, 2024. Reportable scores can take two weeks to process and we may not be able to review any scores that arrive after our deadline.

What is the department code for TOEFL scores?

Our TOEFL codes are 2074 (Institution) and 59 (Department).

What if I am a non-native English speaker and I attended a University in the United States, Canada, Great Britain, or Australia?

Previous studies at a U.S. high school, college, or university are NOT grounds for a language-test waiver. Additionally, previous studies at a non-U.S. English language instruction high school, college, or university are also NOT grounds for a language-test waiver.

Is a GRE score required?

While we require a GRE score with your application submission, we are interested in the applicant’s entire application package, including coursework, statement of purpose, and recommendations. 

Our institution and department codes are:
Institution Code: 2074
Department Code: 0705

Financial Questions

What are the costs for the program?

For budgeting and planning purposes, the tuition for the MADS program for the 2024-2025 academic year is $59,600 plus mandatory student fees of approximately $984. 2025-26 tuition will be finalized and communicated to admitted applicants in Spring 2025.

Do you offer financial aid?

We do not offer a financial aid package for the MADS program. In some cases, we may have very limited scholarships. Subject to eligibility and qualifications, all admitted MADS students will receive the offer to work as an educational assistant or teaching assistant in the Department of Statistics & Data Science. MADS students receive a stipend for their role as educational assistants or teaching assistants.
