……There is a strong correlation between the unemployment rate going up and the number of people utilizing soup kitchens in a given area.

Two variables or occurrences seem to have a strong link between each other.

There is always an effort by sociologists to separate causal from correlational; however correlation can involve causation (ex: educational experience v. success / family income&involvement

EthnographyEthnography

Ethnography1. Firsthand studies of

people using actual observations or interviewing.

• From this research and researchers can get clear first person accounts and evidence of how a specific group functions within a larger society

Downsides are that only small populations can be studied and results cannot be applied to diff. groups even if they hold the same title

Another loss is if the researcher becomes to comfortable they stop being the researcher
