What is a cross-sectional design?

AA study of one specific segment of customers

BA research design that is free from any personal bias

CThe collection of data only once from different respondents at a single point in time ✓ Correct

DA comparison of two or more variables over a long period of time

Correct answer: (C) The collection of data only once from different respondents at a single point in time

Explanation

A cross-sectional design collects data only once from different respondents at a single point in time.

Studying one specific segment of customers describes a market segment, not this design.

Freedom from personal bias is a quality goal, not the definition of cross-sectional research.

Comparing variables over a long period describes a longitudinal, not cross-sectional, design.

It gives a snapshot of the population and is quick and economical to run.

It can show association between variables but cannot easily establish time order.
