Getting started with Tabletop
In this exercise, you will organize
data from a collection and then analyze your data using
stack plots and Venn loop plots. Choose one of the
following, depending on the collection at hand:
Pocket Change
Using the change from everyone's pockets
or a change collection provided by the instructor, create a
database. In your small group, choose at least four fields
to include. These may be name, value, color, diameter,
thickness, shape, or attributes such as ribbed/not ribbed;
round/not round, and so on.
Step One: Create a database
- Double - click the Tabletop icon to
open the program.
- Under the File menu, choose New
Database.Type name as the first field.
- This first field will contain
letters, so choose String as the field type.
(click and hold the button next to the field name, drag
down to String and release).
- Click the check button to register
this field.
- Choose Add Field from the Database
menu.
- Type How many as the next
field, click the check button.
- Choose number as the field
type.
- Add a new field called edged?
and choose Boolean as the field type - this will give you
a true or false entry.
- Repeat until you have at least four
fields.
Step Two: Save the database
- Under the File menu, choose Save New
Database.
- Name the database Pocket Change and
save to the desktop.
Step Three: Add data
- Click the first data cell (in the
Name field).
- Type the name of the first coin.
- Press the tab key to move to the next
field.
When you enter the true/false data, you
need only type a T or Y to enter True; an F or N registers
as False.
