## Introduction

Statistical Science is the science of learning from data. Statistical science plays a large role in data science, which broadly encompasses computational and statistical aspects of managing and learning from large and complex datasets. Statistical theory and methodology have applications in almost all areas of science, social science, public health, medicine, engineering, finance, technology, business, government and industry. Statisticians and data scientists are involved in solving problems as diverse as understanding the health risk of climate change, predicting the path of forest fires, understanding the role of genetics in human health, and creating a better search engine. New ways of collecting, organizing, visualizing, and analyzing data are increasingly driving progress in all fields and have created demand for people with data expertise.

The Department of Statistical Sciences offers specialist, major, and minor programs in Statistics and a specialist program in Data Science. All programs offer training in statistical methods, theory, computation, and communication, as well as an understanding of the role of statistical science to solve problems in a variety of contexts. The specialist program in Statistical Science: Theory and Methods emphasizes probability and statistical theory as underlying mathematical frameworks for data analysis. The specialist program in Statistical Science: Methods and Practice has greater emphasis on collaborative statistical practice. Students in this program combine their study in statistics with a focus in a discipline that relies on statistical methods. The specialist program in Data Science is offered jointly with the Department of Computer Science. Students in this program acquire expertise in statistical reasoning and methods, in the design and analysis of algorithms and data structures for handling big data, in best practices for software design, and in machine learning. The major program in Statistics offers the most flexibility in choice of courses. This program gives students a broad understanding of the methods and computational and communication skills appropriate for effective statistical problem solving. The minor program in Statistics is designed to provide students with exposure and skills in advanced statistical methods.

### Statistical Sciences Programs

### Data Science Specialist (Science Program) - ASSPE1687

**Description:**

The field of Data Science is a combination of statistics and computer science methodologies that enable ‘learning from data’. A data scientist extracts information from data, and is involved with every step that must be taken to achieve this goal, from getting acquainted with the data to communicating the results in non-technical language. The Data Science Specialist program prepares students for work in the Data Science industry or government and for graduate studies in Data Science, Computer Science, or Statistics. Students in the program will benefit from a range of advanced courses in Computer Science and Statistics offered by the University of Toronto, as well as from a sequence of three integrative courses designed especially for the program.

The Data Science Specialist program comprises three fundamental and highly-integrated aspects. First, students will acquire expertise in statistical reasoning, methods, and inference essential for any data analyst. Seconds, students will receive in-depth training in computer science: the design and analysis of algorithms and data structures for handling large amounts of data, and best practices in software design. Students will receive training in machine learning, which lies at the intersection of computer and statistical sciences. The third aspect is the application of computer science and statistics to produce analyses of complex, large-scale datasets, and the communication of the results of these analyses; students will receive training in these areas by taking integrative courses that are designed specifically for the Data Science Specialist program. The courses involve experiential learning: students will be working with real large-scale datasets from the domain of business, government, and/or science. The successful student will combine their expertise in computer and statistical science to produce and communicate analyses of complex large-scale datasets.

Skills that graduates of the program will acquire include proficiency in statistical reasoning and computational thinking; data manipulation and exploration, visualization, and communication that are required for work as a data scientist; the ability to apply statistical methods to solve problems in the context of scientific research, business, and government; familiarity and experience with best practices in software development; and knowledge of current software infrastructure for handling large data sets. Graduates of the program will be able to demonstrate the ability to apply machine learning algorithms to large-scale datasets that arise in scientific research, government, and business; create appropriate data visualizations for complex datasets; identify and answer questions that involve applying statistical methods or machine learning algorithms to complex data, and communicating the results; present theresults and limitations of a data analysis at an appropriate technical level for the intended audience.

**Enrolment Requirements:**

This is a limited enrolment program that can only accommodate a certain number of students. Eligibility is based on the average of a student's grades in CSC148H1 and MAT137Y1/ MAT157Y1 and STA130H1. ( MAT157Y1 grades will be adjusted to account for the course's greater difficulty.)

In addition, students must have completed at least 4.0 FCEs and achieved a minimum grade of 70% in each of CSC148H1, MAT137Y1/ MAT157Y1 and STA130H1.

Students will be assessed based on a competitive average across these courses, and a supplemental application which will be considered alongside their academic results.

Important:

- Requests for admission will be considered in the first program request period only. For detailed program enrolment instructions and application deadlines for restricted programs please click here.
- Due to the limited enrolment nature of this program students are strongly advised to plan to enroll in backup programs.
- Students admitted to the program after second or third year will be required to pay retroactive deregulated program fees.

## About Courses in Statistical Sciences

The statistics course offerings are intended not only for students in statistics programs of study, but also to serve the needs of the many other disciplines that use statistical methods.

- The first year seminar courses, STA198H1 and STA199H1, are designed to provide the opportunity to work closely with an instructor in a small class setting.
- First year students wishing to enrol in a major or specialist program in the Department of Statistical Sciences must take STA130H1, which provides a broad introduction to statistical reasoning, data science, statistical computation and communication.
- The second year foundation courses (STA220H1, STA221H1, STA237H1, STA238H1, STA247H1, STA248H1, STA255H1, STA257H1, and STA261H1) are distinguished primarily by their mathematical demands, as indicated by the prerequisites. Students interested in pursuing more advanced study in probability and theoretical statistics should take STA257H1 and STA261H1. They are the most mathematically rigorous of the 2nd year courses and provide the greatest flexibility when choosing upper-year courses. They are required by students in the specialist programs in Statistical Science: Theory and Methods and Data Science. Students in the specialist program in Statistical Science: Methods and Practice or in the major program in Statistics may instead choose STA237H and STA238H1. Students in computer science programs of study can take STA247H1 and STA248H1. The courses STA288H1, STA220H1 and STA221H1 provide training in statistical reasoning and methods for students in other programs of study, with STA288H1 particularly designed for students in life science programs. Students interested in completing a minor in statistics can combine STA220H1 with STA255H1, which will provide preparation in probability and statistical theory sufficient for many of the upper year courses in statistical methods.
- Pre- and co-requisites are designed to ensure that students have the appropriate preparation for their courses. They are strictly enforced. However, exceptions can be considered for students who have taken an equivalent course at another university. If you have taken courses that are exclusions to pre- or co-requisite courses, though, you should be aware that these are not always equivalent to the requisite courses and may not be allowed.
