Question

psc 41 Assuming that the claim is correct - that a large vocabulary is associated to a large income - generate an alternate explanation. Can you think of one plausible and specific third variable that could account for the relationship?

Answer 1

Answer:

Lower-income people can have a large vocabulary as well, because of a variety of circumstances. To list a few:

The low-income person may have a job that includes a constant contact with highly-educated people.

The low-income person may himself be a well-educated person who holds a job that does not pay a lot, for example: librarian, or social worker.

The low-income person may live in an area with a great degree of demographic diversity, and even by fluent in several languages because of that. This is common in merchants, who may own a small business that only pays enough to survive, but who have a great degree of contact with many sorts of people.
