Let's solve this step by step:

Step 2:
: Understand the definition of an experiment

An experiment is a scientific method that involves: - Manipulating one or more variables - Having a control group and an experimental group - Systematically testing a hypothesis - Controlling other factors that might influence the results

Step 3:
: Analyze each option carefully

Option A: Testing the effectiveness of a new hair product by allowing one group to use it and comparing results against a group that doesn't use it - This involves: * Manipulating a variable (hair product usage) * Having a control group (no product) and experimental group (with product) * Systematically comparing results - This MEETS ALL criteria of a true experiment Option B: Collecting cholesterol readings - This is an observational study - No variable is being manipulated - Simply collecting existing data - NOT an experiment Option C: Calling voters about election issues - This is a survey or poll - Gathering opinions, not manipulating variables - NOT an experiment Option D: Finding monthly burglary numbers - This is a statistical data collection - Observing and recording existing data - NOT an experiment

Step 4:
: Conclusion

The correct answer is A. This is the only option that represents a true scientific experiment with controlled variables and systematic comparison.

Final Answer

A (Testing the effectiveness of a new hair product by allowing one group to use it and comparing results against a group that doesn't use it)
