A hypothesis is used to determine the relationship between two variables, which are the two things that are being tested.
Characteristics of hypothesis in Research Methodology Characteristics of hypothesis: Hypothesis must possess the following characteristics: Hypothesis should be clear and precise. This type of research method might be used to investigate a hypothesis that is difficult to test experimentally. Experimental Research Methods Experimental methods are used to demonstrate causal relationships between variables.
