Steppin’ Out features over 200 artists and crafts people from around the United States selling unique handcrafted items – jewelry, pottery, textiles, metal work, basketry, stained & fused glass, yard art, fine art, furniture, toys, artisan foods and so much more!

Downtown Blacksburg merchants also hold their much-awaited final clearance sidewalk sales during Steppin’ Out. The festival foods you love are provided by downtown restaurants.

Three stages of live performance, both Friday and Saturday, make Steppin’ Out one of this region’s premier arts events.

(1) The Main Stage provides continuous live music on College Avenue and Main Street.
(2) The Acoustic Stage brings folk, contemporary, and utterly unique sounds to the festival area of Main and Lee Streets.
(3) The Community Stage showcases local and regional performers from cloggers to belly dancers. The Community Stage is located in the National Bank of Blacksburg Parking lot on Roanoke Street.

Schedule: Basic

July 27 Saturday Arrival (any time) Dinner for participants, reception at D. Mayo’s home


We anticipate our seminars will run 5-6 hours a day, excluding Sunday (not including lunch and coffee breaks)–beginning no earlier than 9:30. We anticipate a modified schedule on Wednesdays, ending our Seminar 3:30 or 4, (for individual meetings with directors). There will be 5-6 outside speaker evenings, and Sunday (Aug 4) with no scheduled seminar meetings (which doesn’t mean you might not want to create some yourselves). Of course there will be break-out groups and several opportunities for participants to present their own materials.  If participants wish to hold talks on open nights, they are very welcome to do so, but this is optional. We’ll hold a short meeting Sunday Aug. 11 to grant certificates over brunch. This will be immersive as promised.

Please check back for updates.

Posted in Instructions for Applying


FAQS :(3/3)

(0) What if I must miss the first day or two? We may consider an individual who has a good background and can make her case about promoting the goals of this seminar. (The stipend would be adjusted.) We should have recordings of the main sessions. Write to and

(1) What are the Instructions for Applying? 

These are on the first post of this blog. The Cover sheet contents may be found in the menu of pages at the top of this blog. Please type and pdf your responses.

(2) Will I have to have a background in statistics before the seminar?

The main aim of the seminar is to provide such a background. So, the answer is no. You’ll have a chance to describe your background in your application. Some will have stat and no philo, and we might break out into groups with one group working on philo, the other on stat. You can follow our current graduate Seminar on the drop-down page “PhilStat Spring 19” (at the top of the Error Statistics Philosophy blog).

It’s useful to know some probability, and I find it helpful to watch some of the seminars at the free Khan Academy: AP Statistics. Participants are expected to have read at least 3/4 of SIST (Mayo 2018) in advance so that they can participate and keep up with the discussion in our condensed schedule.

(3) Where is Virginia Tech?

Blacksburg, Virginia–in the beautiful Blue Ridge Mts pictured above.

(4) Who can I contact with questions that aren’t answered here (after December 26)?

We will try to cover all conceivable questions in the instructions here (at least by Jan. 3, 2019). However, if you have other questions, please write to (logistics administrator) or using the following subject for your email: SUMMERSEMINARPHILSTAT in capitals.

*(5) Are graduate students eligible to participate? Advanced graduate students working on a dissertation in this area will be considered. Interested participants who aren’t sure if they are eligible to apply should definitely ask.

*Modification (3/3) A Ph.D student already fully responsible for teaching a course in 2019-20, who can show the goals of our Seminar are furthered by how it will alter the material of that course (& the topics of their dissertation), may be considered,

(6) Are individuals who teach in business, statistics or other fields who feel they would contribute to our mission eligible? Yes. Explain in your application how your project or research would bring our goals to fruition.

(7) What if families require larger dwellings? Blacksburg offers a wide-range of summer rentals of houses and apts. We will do our best to facilitate any participant needing such arrangements.

The Statistical Crisis of Science: Where are the Philosophers?

This was published today on the American Philosophical Association blog

“[C]onfusion about the foundations of the subject is responsible, in my opinion, for much of the misuse of the statistics that one meets in fields of application such as medicine, psychology, sociology, economics, and so forth.” (George Barnard 1985, p. 2)

“Relevant clarifications of the nature and roles of statistical evidence in scientific research may well be achieved by bringing to bear in systematic concert the scholarly methods of statisticians, philosophers and historians of science, and substantive scientists…” (Allan Birnbaum 1972, p. 861).

“In the training program for PhD students, the relevant basic principles of philosophy of science, methodology, ethics and statistics that enable the responsible practice of science must be covered.” (p. 57, Committee Investigating fraudulent research practices of social psychologist Diederik Stapel)

I was the lone philosophical observer at a special meeting convened by the American Statistical Association (ASA) in 2015 to construct a non-technical document to guide users of statistical significance tests–one of the most common methods used to distinguish genuine effects from chance variability across a landscape of social, physical and biological sciences.

It was, by the ASA Director’s own description, “historical”, but it was also highly philosophical, and its ramifications are only now being discussed and debated. Today, introspection on statistical methods is rather common due to the “statistical crisis in science”. What is it? In a nutshell: high powered computer methods make it easy to arrive at impressive-looking ‘findings’ that too often disappear when others try to replicate them when hypotheses and data analysis protocols are required to be fixed in advance.

This is an important and illuminating study on misreporting results of medical trials, along with inaccurate explanations (by authors) of what was done (as a result of letters by Goldacre’s group).
