2000 Curriculum Guidelines for Undergraduate Programs in Statistical Science
The American Statistical Association endorses the value of
undergraduate programs in statistical science, both for statistical
science majors and for students in other majors seeking a minor or
concentration. This document provides guidelines for development of
curricula for such programs.
Principles
Undergraduate programs in statistics are intended to equip students
with quantitative skills that they can employ and build on in flexible
ways. Some students will plan graduate work in statistics or other
fields, while others will seek employment after their first degree.
Programs should be sufficiently flexible to accommodate varying goals.
Undergraduate programs are not intended to train professional
statisticians, though some graduates may reach this level through work
experience and/or further study.
Institutions vary greatly in the type and intensity of programs they
are able to offer. The ASA believes almost all institutions can provide a
level of statistical education that is useful to both students and
employers. We encourage flexibility in adapting these guidelines to
institutional constraints. In many cases, statistics minors or
concentrations for quantitatively oriented students in fields such as
biology, business, and behavioral and social science may be more
feasible than a full statistics major.
Undergraduate statistics programs should emphasize concepts and tools
for working with data and provide experience in designing data
collection and analyzing real data that go beyond the content of a first
course in statistical methods. The detailed statistical content may
vary, and may be accompanied by varying levels of study in computing,
mathematics, and a field of application.
Though statistics requires mathematics for the development of its
underlying theory, statistics is distinct from mathematics and uses many
nonmathematical skills; thus, the curriculum must be more than a
sequence of mathematics courses. It is essential that faculty trained in
statistics and experienced in working with data be involved in
developing statistics programs and teaching or supervising courses
required by the programs.
Skills Needed
Effective statisticians at any level display a combination of skills
that are not exclusively mathematical. Programs should provide some
background in the following areas:
Statistical - Graduates should have training and experience in
statistical reasoning, in designing studies (including practical
aspects), in exploratory analysis of data by graphical and other means,
and in a variety of formal inference procedures.
Mathematical - Undergraduate major programs should include
study of probability and statistical theory, along with the prerequisite
mathematics, especially calculus and linear algebra. Programs for
nonmajors may require less study of mathematics. Programs preparing for
graduate work may require additional mathematics.
Computational - Working with data requires more than basic
computing skills. Programs should require familiarity with a standard
statistical software package and encourage study of data management and
algorithmic problemsolving.
Nonmathematical - Graduates should be expected to write
clearly, speak fluently, and have developed skills in collaboration and
teamwork and organizing and managing projects. Academic programs often
fail to offer adequate preparation in these areas.
Substantive area - Because statistics is a methodological discipline, statistics programs should include some depth in an area of application.
Curriculum Topics for Undergraduate Degrees in Statistical Science
The approach to teaching the following topics should:
- Emphasize real data and authentic applications
- Present data in a context that is both meaningful to students and indicative of the science behind the data
- Include experience with statistical computing
- Encourage synthesis of theory, methods, and applications
- Offer frequent opportunities to develop communication skills
Statistical Topics
- Statistical theory (e.g., distributions of random variables,
point and interval estimation, hypothesis testing, Bayesian methods)
- Graphical data analysis methods
- Statistical modeling (e.g., simple, multiple, and logistic regression; categorical data; diagnostics; data mining)
- Design of studies (e.g., random assignment, replication,
blocking, analysis of variance, fixed and random effects, diagnostics in
experiments; random sampling, stratification in sample surveys; data
exploration in observational studies)
Mathematical Topics
- Calculus (integration and differentiation) through multivariable calculus
- Applied linear algebra (emphasis on matrix manipulations, linear
transformations, projections in Euclidean space, eigenvalue/eigenvector
decomposition and singular-value decomposition)
Probability
- Emphasis on connections between concepts and their applications in statistics
Computational Topics
- Programming concepts; database concepts and technology
- Professional statistical software appropriate for a variety of tasks
Nonmathematical Topics
- Effective technical writing and presentations
- Teamwork and collaboration
- Planning for data collection
- Data management
Electives - There are many electives that might be included in
a statistics major. As resources will vary among institutions, the
identification of what will be offered is left to the discretion of
individual units.
Practice - When possible, the undergraduate experience should
include an internship, senior-level "capstone" course, consulting
experience, or a combination of these. These and other opportunities to
practice statistics should be included in a variety of venues in an
undergraduate program.
Curriculum Topics for Minors or Concentrations in Statistical Science
The core of a minor or concentration in statistics should consist of the following:
- General statistical methodology (statistical thinking, descriptive, estimation, testing, etc.)
- Statistical modeling (simple and multiple regression, diagnostics, etc.)
- Exposure to professional statistical software
The number of credit hours for minors or concentrations will depend
on the policies set by the academic units involved. Additional topics to
complete the required number of credit hours could be chosen from some
nonexhaustive list (e.g., mathematical statistics, design of
experiments, categorical data analysis, time series, Bayesian methods,
probability, database management, a capstone experience). Courses from
other departments with significant statistical content might be allowed
to count toward a statistics minor or concentration, though the content
of such courses must differ substantially from the others.
