The main goal in this lab is to introduce the student to the ideas involved
in analyzing data from an observational study. The student will be exposed
in a metaphorical way to the process of data collection. Once the data
is collected the student will read look at rates in bar charts
including segmented bar charts and conditional bar charts.
The student will explore the difference
between association and causation. Confounding factors will be
controlled for and the student will see what a difference it makes.
The student will consider the effect of intervention with respect to
different kinds of variables.
How To Play
This lab is intended to be much like a game. The student operates
Fritz, a new hire at a hospital, and is interested in what factors
are important in the health of newborn babies. Information can be
gleaned through interactive
dialogs with various experts, docents, and visitors in the hospital.
Plots, documents, and transcripts of dialogs are collected in Fritz's
binder, and reports are filled out at various stages in the
investigation. The analyst in the hospital guides Fritz by giving
instructions and accepting reports.
