Since you did not tell us what Maria's hypothesis was or how she tested it, we cannot provide an answer.
The purpose of controlling the environment when testing a hypothesis is ultimately to get a reliable result to the study.
By testing.
the process is to know what they hypothesis means
No, science does not advance without testing hypotheses.
You would need to tell us about the data, the hypothesis and so on for us to be able to answer.
In statistics, we have to test the hypothesis i.e., null hypothesis and alternative hypothesis. In testing, most of the time we reject the null hypothesis, then using this power function result, then tell what is the probability to reject null hypothesis...
forming a hypothesis is when you come up with an educated guess.. what you think it may be . testing a hypothesis is when you're testing to see if someone else's guess is right.
examining/ experimenting/ testing/ verifying... it depends on the type of hypothesis to an extent I think.
Since you did not tell us what Maria's hypothesis was or how she tested it, we cannot provide an answer.
A hypothesis is a suggestion of a way to explain something. If the hypothesis is tested and confirmed, it can advance to the status of theory. The conclusion of testing a hypothesis will be either that the hypothesis is confirmed, or it is not confirmed.
The purpose of controlling the environment when testing a hypothesis is ultimately to get a reliable result to the study.
Rejecting a true null hypothesis.
