Scientific Power

 Exploratory:

Exploratory: the first thing you see is objects and traces. They are the “trail” to follow.

Descriptive: the more you see, the more you describe. But this is the end of the line for scientific power.

Steps

1. Identify population/topic
2. Choose recording tool
3. Record audio-visual
4. Analyze, Interpret, and Report

Advantages

1. Useful when people are unwilling to answer surveys
2. Reveal habitual behavior
3. Useful for people who are not articulate (children) (or lost in translation)
4. Allows to triangulate with other methods, to check validity of results

Disadvantages

1. Lack of context
2. Physical evidence is limited in objects of measurement
3. Time-consuming
4. Hazardous (ex: gangs, drug rings)
5. Ethical considerations if researcher needs to be covert
