What is the difference between hypothesis and hypothesis testing?

	In order to comprehend a phenomena, researchers evaluate and gather data in a systematic manner. Both hypothesis and hypothesis testing are two different things but they’re both related in some ways. Additionally, hypotheses are statements that introduce research questions and speculate about the outcomes they could generate. The researcher  can only hypothesize what could be true about a population, but which they cannot prove to be true. In contrast,  hypothesis testing is the pillar that leads to authentic research findings. The researchers can use statistics to test the assumptions about the topic in a systematic way. Also, scientists and researchers frequently employ it in order to put certain assumptions to the test. Researchers use hypothesis testing to find out if the sample supports the idea about the population.

Differentiate hypothesis and prediction.

Hypothesis and prediction are two different things and they don't even resemble each other at all. The hypothesis should have a solid reasoning, which is frequently backed up by prior research. In scientific terms, a hypothesis is an educated guess as to how two or more variables could be related. It's a particular, testable prediction about what you expect to happen in a study. In contrast, prediction is where someone can only make conclusions based on their limited understanding of the topic.  If the subsequent events do not match up, the prediction is inaccurate. A prediction is nothing more than a wild guess based on nothing but conjecture. To put it simply, a prediction is essentially a guess about the future, whereas a hypothesis is a proposition put forward for the explanation.

What is the purpose of hypothesis testing?

In statistics, hypothesis testing is a crucial approach. It's possible to test two opposite hypotheses in order to see which one is supported by the sample data. Hypothesis testing is a statistical technique that enables the identification of significant information. The purpose of hypothesis testing is to let a person decide between two different hypotheses and whether a null hypothesis should be accepted or rejected. The researchers will observe that they don't say that the alternative hypothesis is rejected or fails. Also, hypothesis testing is not intended to prove or contradict anything. To summarize it all up, hypothesis testing is an essential method for evaluating the efficacy of various solutions and ideas.

What should methodology contain?

An important component of presenting the findings is writing the methodology. Readers can assess the research's reliability and validity by reading the methodology section of the paper. The procedures and methods used to gather and analyze data are discussed in the methodology. Furthermore, it specifies the particular instruments the researcher must use to complete the research. In order to support the research methodology, the researchers must demonstrate that they are knowledgeable about various methods. Additionally, they need to be aware of the risks and limitations of the data collection and analysis method, and demonstrate the competence to use various data analysis.
