- Thanks to Dennis Roberts, Arnie Kahn, Frank Bokhorst, and Antoine Morin
- for their responses to my query about WHAT CONCEPTS should be included
- in the various flavors of intro course.
-
- Dennis writes that we should start them collecting and looking at some
- data, then let them discover statistical models/summaries. Descriptive
- statistics units which appear in the first unit of almost every intro
- stat book would be moved down a bit.
-
- This is an interesting thesis. It raises the question of "What opening
- gambit works best?" I have talked to others who think starting with a
- data collection exercise or a data exploration exercise is a dynamite way
- to go. I have also used Freedman, Pisani, and Purves opening gambit of
- describing some interesting experiments, surveys, and observational studies
- to capture the class' attention. (Note. FPP actually do not introduce
- surveys until chapter 19. However, those people that I have talked to in
- the last year or so who use the book correct this oversight by including
- an introduction to surveys along with experiments and observational studies.)
-
- Bokkie asked if I meant anyone instead of everyone in my category 1. Actually
- I did mean everyone in the sense that there probably are some concepts that
- we would like in every course - algebra based or calculas based.
-
- This raises an additional issue. What prerequisites should we require? I
- have implied that in some courses college level algebra should be required
- and in others one should be able to take advantage of a calculus prerequisite.
- Should we have a category of courses for ANYONE? What does this mean? High
- school algebra, general math, walking and breathing (but not necessarily at
- the same time)?
-
- BRIEF SYNOPSIS of additional key phrases in the responses to date-- gauging
- significance of differences, sampling, estimating variance, precision vs.
- accuracy, statistical vs. practical significance, p values, power and relia-
- bility of tests.
-
- More responses welcomed.
