The key purpose of any single experiment is to - correct answer ✔✔Test a hypothesis and see if
the evidence supports it.
Which of the following statements about the scientific method is correct? - correct answer
✔✔An experiment compares two groups that differ in only one way. That differ nice is the
variable and is what is being tested.
