Editing Operationalization (section)

===Anger example===
For example, a researcher may wish to measure the concept "anger." Its presence, and the depth of the emotion, cannot be directly measured by an outside observer because anger is intangible.  Rather, other measures are used by outside observers, such as facial expression, choice of vocabulary, loudness and tone of voice.

If a researcher wants to measure the depth of "anger" in various persons, the most direct operation would be to ask them a question, such as "are you angry", or "how angry are you?".   This operation is problematic, however, because it depends upon the definition of the individual.  Some people might be subjected to a mild annoyance, and become slightly angry, but describe themselves as "extremely angry," whereas others might be subjected to a severe provocation, and become very angry, but describe themselves as "slightly angry."  In addition, in many circumstances it is impractical to ask subjects whether they are angry.

Since one of the measures of anger is loudness, the researcher can operationalize the concept of anger by measuring how loudly the subject speaks compared to his normal tone. However, this must assume that loudness is a uniform measure. Some might respond verbally while others might respond physically.
