Random Definition

Being or relating to a set or element in which each set or element has an equal (non-zero) probability of occurring.

In market research, random refers to a method of selection or assignment where each member of a population has an equal and independent chance of being chosen. It’s commonly used in sampling and experimental design to eliminate bias and enhance the validity of results.

Who relies on random methods in market research?

Research firms, data scientists, academic researchers, polling organizations and government agencies use random methods to draw statistically valid conclusions and ensure representative insights.

What are key aspects of random selection in market research?

• Equal probability of selection.
• Reduction of selection bias.
• Foundation for probability sampling.
• Enhances external validity.
• Often implemented using random number generators or software.

Why is random selection important in market research?

Random selection ensures that results can be generalized to a broader population, supports credible and defensible findings and reduces the influence of personal or systemic biases in the data collection process.

How do market researchers use random selection?

Researchers use random techniques to select survey participants (e.g., random digit dialing, stratified random sampling), assign participants to control or test groups in experiments and run simulations or A/B tests to assess consumer responses or behavior patterns.
