Formulating a Hypothesis
Formulating a hypothesis needs earlier evidence and should be testable. The hypothesis should be stated clearly and briefly for readers to understand it easily. To develop a hypothesis, the researcher needs to have an extensive and broad knowledge on the topic and look deeply into the past articles and journals on the same topic.
