| HOMEWORK Day1 --Leave under my door, Mac 102: Pretest and Student questionnaire, if not finished in class today. --Activstats--Getting Started, do front page. Do Ch. 1, Introduction Do Ch. 2, Data & Measurement: Do the Circle Experiment, p. 2-2 top (in SPSS version, 2-3 top in Generic) and save your results. Looking at your data / learning about SPSS or DataDesk is optional. Remember, variables hold measured information on individual cases. In this dataset we measured: Variables: * the time between mouse clicks (time) * the size of the circle (size) * the distance between the circles (distance) * by how much you missed the center of the circle (missBy) * whether the trial was for your right or left hand (hand) * the color of the cirle recorded in text (color) * and as an index number (color Index) * the distance in the x direction between the two circles (dX) *the distance in the y direction between the two circles (dY). Hand in: B) Which are quantitative, which categorical ? Bring Circle data to class & be prepared to discuss: What questions could we ask about your performance? |

Intro Stats Text &
Activstats for SPSS (bundled) Prof. Velleman's
life
work.
Intro Stats:
I really like the philosophy of this text. As a first edition,
there are still a few bugs left; don't be afraid to disagree with the
author or the solutions manual.
Activstats
goes through the concepts one by one,
with an activity, exercises, self-tests. You can stop, start,
repeat
as often as you like. Eliminates the "I dropped my pencil and
missed
3 definitions" problem with lectures, also class diversity problem.
SPSS vs. DataDesk: Statistical Packages...
SPSS is research-level
package standardized on by social sciences. We will learn how to
use (some of) it this term.
DataDesk (student
version) comes with Activstats bound in book. Has a powerful set of
tools for
manipulating and visualizing data, as well as doing standard
statistics. Learning it is optional. (But if
you learn 2 stats packages, the next will be easy!)
Take notes! (Book and disk).
Questions? (answers) More than once through!
Long-term memory--repetition at intervals, several senses
(write it down).
