Data
Data
Table:
This will occur WHILE YOU ARE DOING YOUR EXPERIMENT!!! You will record all data into a rough draft
of a data table in your science fair logbook.
A data table is how you will organize your data. While you record your data, make sure you
record observations and other notes in your logbook. After the experiment, take the time to
reconstruct your data table neatly, and figure out your averages. On your backboard you may end up using Excel
and come up with a table that looks like the one below.

Graph:
After you
make a data table, you will create a graph.
A graph is a visual representation of your data. Below is an example of a graph and everything
you need to remember when making a graph. Most of the time, you will only
graph averages.
