Question

9. For each scenario, would you gather data by using a survey, an experiment, or an observational study? Why?

A) You want to know if playing certain types of music affects the way plants grow.
B) You want to know what kind of plants people prefer to grow in your town.
C) You want to know if using a certain kind of fertilizer will help the dying tree in your yard.

PLEASE PLEASE EXPLAIN WHY

Answer 1

A) experiment B) Survey C) observational study

Explanation:

A could either be experiment or observation but you are experimenting with different types of music and plants so experiment makes more sense to me.

B is a survey because you are asking a group about a topic and recording the answer which is essentially a survey.

C is an observation because you are checking to see improvement, no improvement, or stays the same ie: meaning you have to observe what happens before and after
