As a domain expert in the field of scientific inquiry, I am well-versed in the importance and application of hypotheses in the scientific process. The development and testing of hypotheses are fundamental to advancing knowledge and understanding in any scientific discipline. Here's a comprehensive look at the purpose of having a hypothesis:

1. Formulating Questions: A hypothesis begins with a question, often one that arises from an observation or a gap in existing knowledge. It's a way to focus the research and to explore the unknown systematically.

2. Predictive Power: A hypothesis should be predictive. It allows scientists to make educated guesses about what might happen in a particular situation. This prediction is what will be tested through experiments or further observations.

3. Operationalization: It provides a way to operationalize abstract concepts. In other words, it translates a scientific question into a form that can be tested empirically. This is crucial because it allows researchers to measure and manipulate variables in a controlled manner.

4. Independent and Dependent Variables: A hypothesis involves at least two variables, one independent and one dependent. The independent variable is what the researcher manipulates, and the dependent variable is what is measured. The hypothesis predicts a relationship between these two.

5. Testable Statements: Hypotheses are formulated as testable statements. They must be clear, precise, and capable of being supported or refuted through experimentation or observation.

6. Driving Experiments: The hypothesis is the driving force behind the design of an experiment. It dictates what needs to be controlled, what needs to be measured, and how the data should be analyzed.
7.
Falsifiability: A good hypothesis is falsifiable, meaning it can be proven false. This is a key criterion established by philosopher of science Karl Popper. It's through the potential of being proven wrong that science advances.
8.
Communication: Hypotheses facilitate communication among scientists. They provide a common ground for discussion and a basis for further research. If a hypothesis is not supported by evidence, it can lead to the refinement of ideas and the generation of new hypotheses.
9.
Progress of Science: Ultimately, the testing of hypotheses is what drives the progress of science. It's through this iterative process of hypothesis generation, testing, and refinement that scientific theories are developed and knowledge is advanced.
10.
Risk Management: In applied research, hypotheses can also serve to manage risks by predicting outcomes before costly or irreversible actions are taken.

Now, let's proceed with the translation into Chinese.

A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question. ... The first variable is called the independent variable. This is the part of the experiment that can be changed and tested.read more >>
