Lee wants to make sure she understands the components of a good scientific investigation. She knows that it should be controlled and have a large sample size. Also, she thinks that the results should be communicated to other scientists. Which is another component that is necessary for a good investigation?

The other component is that her investigation must be replicated by other scientists.

Explanation:

Lee's understanding of good investigation includes that her investigation should be controlled and have a large sample size. And, that the results should be communicated to other scientists as well. The another main component required in making an investigation good and successful is that it should be replicated by other scientists.

In science, the term replication can be defined as a repeated experiment having same results. When an investigation is experimented repeatedly and gives the same result everytime, it denotes the success of that investigation. If repeated experiment failed to produce same result it means that investigation is not accurate.

So, correct answer is that her investigation must be replicated by other scientists.
