Answer;
-Similar results should be obtained when the experiment is repeated.
Step-by-step explanation;
-A valid experiment is repeatable; when you repeat your experiment, it should yield the same results. It is also reproducible. Someone else should be able to perform your experiment and get the same results.
-If other scientists get different results, then you have overlooked one or more important parts of your experimental design, like a variable you didn't take into account that influences the outcome.
