Polygraph Information

by Kaitlyn Guenther

This is a school project that I did for my Forensic Science class in grade 10.  All of the information is about polygraph machines. 

Polygraph, meaning "many writings", is derived from the Greek language.  In Greek the word "poly" means "many", and the word "graph" means "writings".

About the Polygraph Machine:

• History of the Polygraph Machine

• Polygraph Test Results

• The Accuracy of Polygraph Testing
