Abstract
In this article, variables, hypotheses and assumptions have been made the subject of research because they are the backbone of any research. This is often mistaken for not knowing the types of variables or the relationship between these variables is not stated. For variables, it is necessary to first identify it and then describe the relationship between them, and if these can be tested, then it becomes the hypothesis. The same mistake has been made in the case of hypotheses that its types are not recognized and that's why most researchers are worried. And most importantly, researchers generally do not distinguish between hypotheses and assumptions and do not know what the two are.
