If they leave the classroom, the students feel free to break the rules and talk more, making the room i measure the noise level in a classroom when a teacher is in it and when she leaves the room, then i will see that the noise level is higher when my teacher is not in my if my hypothesis is wrong?

Generally used in quantitative research studies, it's an educated guess or prediction about the relationship between two variables.
It must be kept in mind that within the scope of one study, the presence of a number of research questions will affect and potentially increase the complexity of both the study design and subsequent statistical analyses, not to mention the actual feasibility of answering every question. Process starts with formulating a good are not the hypotheses you are looking we are new to hypothesis testing, we tend to start with hypotheses like these:Fixing the hard-to-use comment form will increase user engagement. For example, let us say that you hypothesize that earthworms do not exist in places that have very cold winters because it is too cold for them to survive.
