What is Wellesley's QR requirement and how do students satisfy it**?**

The Quantitative Reasoning degree requirement has two parts, a **Basic Skills component** and a **Data Literacy component**. All students must satisfy both components of the requirement.

**Basic Skills**

The **Basic Skills component **of the QR degree requirement is satisfied either by passing the QR Assessment by the end of Orientation or by passing QR 140, the basic-skills course that builds mathematical skills in the context of real-world applications. Students are required to satisfy the Basic Skills component of the QR degree requirement in their first year so that they may enroll in the many courses for which basic quantitative skills is a prerequisite.

Learning goals for the Basic Skills component of the QR requirement, and for the basic skills course, QR 140, are: Students will learn to utilize logic, mathematics, and statistics to make decisions as they encounter real world problems in their later coursework, in their future employment, and in their everyday lives as consumers and citizens. By the end of the semester, students will be able to complete the following tasks.

- Set up and solve real-world problems that require multi-step calculations using unit conversions with both familiar and unfamiliar units, scaling, and proportions.
- Calculate with and describe percentages in two-way tables.
- Identify, set up, and solve real-world problems involving linear and exponential growth, using logarithms where appropriate.
- Interpret and perform calculations with numbers in scientific notation.
- Design and carry out multi-step "back-of-the envelope estimations," incorporating geometric formulas for area, volume, and surface area where appropriate.
- Calculate and interpret the mean, median, and standard deviation, and associate these quantities with histograms and written descriptions of data.
- Create spreadsheets to model real-world scenarios and interpret real-world data.

**Data Literacy**

The **Data Literacy component** of the QR degree requirement (formerly known as the "QR overlay requirement") is satisfied by passing a designated Data Literacy course or by receiving AP credit in Statistics (which is equivalent to completion of QR/STAT 150: Introduction to Data Literacy). All Data Literacy courses are designed, at least in part, to teach students how numerical data are analyzed and interpreted in a specific academic discipline. The Committee on Curriculum and Academic Policy has designated individual courses in fields from across the curriculum as ones that satisfy the Data Literacy requirement. Students may complete the Data Literacy requirement at any time during their time at Wellesley. *All Data Literacy courses may also be used to satisfy a distribution requirement.*

Learning goals for the Data Literacy component of the QR requirement are: Students should learn to identify and construct questions that can be answered with data, to select appropriate methods for collecting and analyzing relevant data to address these questions, and to describe both the conclusions and limitations of such analyses. They should work with their own data and read, interpret, and evaluate other people’s work. By the end of the course, students should be able to complete the following tasks.

- Frame appropriate empirical questions or hypotheses.
- Collect or acquire relevant data, addressing possible biases in the data collection, and read and evaluate the works of other people that are based on data.
- Recognize and explain the role randomness plays in designing studies and drawing conclusions.
- Present data with appropriate graphical displays and numerical summaries, and interpret data presented in such formats, considering what such summaries do and do not reveal.
- Apply appropriate analytical techniques to answer the underlying empirical questions, and interpret and describe the meaning of such analyses when used by others.

### Data Literacy Course Options

Wellesley College offers a range of courses that can be used to satisfy the Data Literacy component of the Quantitative Reasoning degree requirement. These **courses** include introductory statistics courses offered within a variety of disciplines, including Biological Sciences, Economics, Sociology, Political Science, Psychology, and Mathematics and Statistics. Other Data Literacy courses include significant emphasis on data and statistics but do not focus solely on statistical analysis and are offered across the curriculum in departments including Art History, Astronomy, Environmental Studies, and Geosciences. The complete list of currently offered courses that satisfy the Data Literacy requirement can be found below. Please see the full course descriptions under each department or program for details on prerequisites and the applications emphasized in each course. Note that: (1) All Data Literacy courses offered at Wellesley require satisfaction of the Basic Skills component of the Quantitative Reasoning requirement as a prerequisite. (2) A single course on the list below can be used to fulfill *both* the Data Literacy component of the Quantitative Reasoning requirement *and* a distribution requirement.

Introductory statistics courses that can be used as prerequisites for further study in statistics are indicated with a ***** in the list below. Because AP credit in Statistics is equivalent to completion of QR/STAT 150: Introduction to Data Literacy, which cannot be used as a prerequisite for higher-level courses in statistics, students with such AP credit who wish to continue their study of statistics must enroll in one of the starred introductory statistics courses on this list. Interested students should consult individual departments or programs for details on the various introductory statistics course options and for suggestions about choosing an appropriate first course.
