An important step in the scientific method is the communication of our results, it is a way of sharing and announcing to the world what we have obtained and how we have obtained it. The presentation of the results can be done through various means: -In written form: in theses, articles in scientific journals, in press articles, on informative posters, in congresses. -In an audiovisual way: in congresses, symposia and conferences, scientists have the opportunity to present their work and establish an exchange of ideas with other researchers. Communication of findings The data obtained through experimentation need to be analyzed in light of the proposed hypotheses and predictions. The analysis of results allows us to accept and reject the proposed hypotheses, reformulate the models and suggest new procedures. ANALYSIS OF RESULTS Observation is noticing or perceiving aspects of nature. Although it is the first step of the scientific method, it is immersed in the entire process of science, from the recognition of a natural phenomenon to the proposal of a solution and the observation of the results after an experiment. OBSERVATION SCIENTIFIC METHOD STAGES EXPERIMENTATION An experiment is a test or trial where conditions are controlled to determine the validity of a hypothesis. In a scientific experiment, physical objects, chemical compounds, or biological species are chosen for study, and devices are used to measure the variables. The results of the experiments have to be reproducible by other researchers under the same experimental conditions. HYPOTHESIS PREDICTIONS Predictions are the expected consequences of hypotheses. According to Mario Bunge, prediction is the deduction of particular consequences: -Anticipate new knowledge: when we predict something objectively and accurately, we are providing new information that can be corroborated. -Test theory: We can compare predictions with prior knowledge. -It is a guide for action: the forecast of an event helps the selection of activities in an investigation The hypothesis is a likely explanation for an observation or an attempt to solve the problem. We have to test the hypothesis through experiments, that is, show that it is true or false. In this way we can differentiate a hypothesis from a belief. Saying "gastritis is imaginary" is not a hypothesis, since an experiment cannot be designed to test whether this is true or not. When we raise a hypothesis we are forced to think and invent an explanation or solution. It can be easy or difficult, it can be a single hypothesis or several, the important thing is to try to explain what we are observing.
