The measurement was done by using abusive words on them to record how their will behave. Those that did not react or has a very mild reaction to it were recorded to have zero to 1 level of aggression, which is known as low aggression level. Those that reacted to the abuse by abusing back or forbidden the abuse, without shouting or being harsh were recorded to have 2 to 4 level of aggression, which is known as medium aggression level. While those that reacted in a harsh manner by shouting and abusing back in a manner that shows their are ready to fight, were recorded to have 5 to 10 level of aggression, which is known as high level of aggression.
The measurement used in this example is Categorical and the type of measure been used called Behavioral measure.
