What types of cases are best investigated with survey rather than an experiment

What are people's favorite colors? How does the color purple make people feel? Something like that

Hi!

We experiment by following scientific principles, and the scientific method. It's through this method that we reach scientific, credible answers which are factual.

In some cases, an experimental question cannot be answered via experimentation. This happens when the question at hand is something that cannot be explained or proved scientifically.

These questions will be subjective and will vary depending on the person. Such questions will ask things like 'What is everyone's favourite animal?'

For this question, we can't exactly answer it scientifically. Therefore, we will not carry out scientific experimentation onto it.

This is when we will use a survey, instead of an experiment. 

Hopefully, this helps! =)
