Answer:
Social work practitioners need to understand methods so they can discriminate strong from weak studies.
Explanation:
The experience that people have in their life can be strongly influence by their wealth, religion, ethnicities, race, and cultural background.
So when researchers make a measurement standard and assume that it is applicable to all people with different experience, the data that collected from the studies tend to be really weak and cannot be generally applicable. This is where social work practitioners come in and help the researchers provide a proper methodology to address the differences.
