Short answer

A jeans company observing the color of jeans most people choose.

Step-by-step solution

Step 1. State the concept for observational studies.

A type of study in which individuals are observed or certain outcomes are measured. No attempt is made to affect the outcome.

Cohort studies and case-control studies are two types of observational studies.

Step 2. Explain with an example.

A real-world example of an observational study is as follows:

A jeans company watches customers as they select jeans and notes the color of jeans they select the most. They conclude that most people prefer blue jeans to any other color of jeans.
