Question

which characteristic should a good scientific question have? it should lead to a hypothesis that is not testable. it should have a very broad focus with many variables. it should repeat a question that the researcher has answered before. it should be based on observations instead of just imagination.

Explanation:

A good scientific question should be based on real - world observations to be valid and testable. A question leading to a non - testable hypothesis is not useful in science. A very broad question with many variables is hard to study effectively. Repeating an already - answered question is not productive.

Answer:

It should be based on observations instead of just imagination.
