Statistical Literacy studies statistics used as evidence in everyday arguments. Statistical literacy is closely related to Numeracy, Quantitative Literacy and Statistics. Stat Lit focuses more on observational studies than experiments, more on two-group comparisons than correlation, more on context and multivariate thinking than chance, and more on ordinary-language than on algebraic-formulas. Although "association doesn't prove causation" in observational studies, the decision-related question is how much support does a statistical association give for inferring a direct causal connection. This site focuses on that evaluation. "Statistical literacy, the ability to follow and understand arguments from data..." For All Practical Purposes. COMAP "What everyone needs [from statistics] is...called statistical thinking or statistical literacy, a crucial component of quantitative literacy." Lynn Steen For background, read "Telling the Truth about More Damned Lies and Statistics" by Joel Best, Chronicle of Higher Education. Print version.

Paul Rosenbaum's
classic Observational Studies is out in an expanded 2nd edition. This book is
a great reference. 
Tony Griffith, Math Instructor,
Westminster School. Online Feedback. I agree with the premise [of QL], but
..I teach high school math at a prep school.... Does the
admissions office at Amherst prefer a kid who can discuss Simpson's
Paradox or simplify a rational function? Does the SAT 2 reward a kid
who can understand Arrow's Impossibility Theorem or factor a cubic
function?
Milo
Schield participated in
"IASSIST
has a significant role to play in helping nurture new
generations of data service providers who can help build a persistent
culture of statistically-literate students, researchers and
professionals. And may this wave of commitment to and
enthusiasm for the cause of statistical literacy thrive!!"

Milo
Schield, Augsburg College, (shown with Louise Corti, IASSIST
Europe) argues that librarians interested in information literacy and data librarians interested in
data literacy should consider teaching statistical literacy since all
three involve critical thinking and since many social science arguments
involve statistics.

David Bressoud, Macalester College. In his keynote, "Core Concepts in QL", Milo Schield argued that QL must have core
concepts "that non-math faculty can understand easily, use regularly and
teach effectively." 
Danny
Kaplan, Macalester College, reviewed using everyday news stories in a
Quantitative Methods for Public Policy course . Policy
Topics: Response to Global Warming, Mad Cow Disease, Immigration and
Taxes. Quantitative topics that span policy topics: rates,
growth, trade-offs, detection and sampling. Average vs
Marginal Rates.

Dean, Scott Bierman, hosted the two-day Associated Colleges of the
Midwest (ACM) workshop. He introduced speakers Joel Best (author
of Damned Lies and Statistics) and Bill Seagraves (Associate Dean
of Yale College). He reviewed data obtained in the use of
quantitative measures in
student portfolios.
Milo
Schield, Augsburg College, analyzed some 500 words that involve quantity
without specifying a number. E.g., many, most, few and some.
Schield argued that students avoid using more precise measures (rates
and percentages) because they did not know how to describe or compare rates
and percentages. Includes Schield's 2004 list of the
top 25 books on Statistical Literacy.

for early statistics courses should "provide a serious introduction to
graphical data analysis, at the expense of some traditional parametric
inference." In "

Jerry
Moreno's goal: "to produce liberal arts students who are
able ... to read a newspaper more intelligently." "We cannot afford to offer two intro courses." "Our
task is to define a few basic core statistics concepts ...and then build one course around those core concepts."

John McKenzie,
Babson College, reported on core concepts: Variability (96%), Association-causation (82%),
Randomness (77%), Significance: practical / statistical (77%), Data collection (75%),
Sampling
distributions (71%) and Hypothesis tests (64%). John classified
courses as "statistical
literacy-reasoning-thinking" (concepts), applied stats (applications,
service) & math. statistics (theory).
The
8th annual session on Statistical Literacy was hosted by Milo Schield at
the ASA meeting in Minneapolis. Speakers included Lewis Cope
(left, Jane Miller (right), Marc Isaacson (below), Chris Olsen (lower

the session. Lewis gave an animated presentation titled
Marc
Isaacson, Augsburg College, reviewed the Statistical Literacy course
first offered by Capella University in April 2005 using Schield's Statistical Literacy
textbook. Students found this course "very demanding" but "very
satisfying." They ranked this course 2nd among their 15 Gen Ed
courses in challenging students to think
critically about the subject matter.
Chris
Olson, Cedar Rapids Community Schools, presented a paper, "Epidemiology
as a Context for Teaching Confounding in Introductory Statistics." "surely the most needed
discussion about everyday inference is about what is probably the
greatest source of inferential error the confusion of correlation with
causation, as well as a general ignorance of ... confounding." 
Tom
Burnham, Cognitive Consulting, presented a paper titled "An
Online Program for Decoding Ordinary English Descriptions and
Comparisons of Percentages and Rates." This
Milo
Schield, Director of the W. M. Keck Statistical Literacy project at
Augsburg College, reviewed the prevalence
of chance-related terms on the web and used these prevalences to
identify those topics that should be part of a general statistical
literacy course. Includes unusual topics such as evolution, ESP and a
Bayesian approach to statistical significance.
