The independent variable is expected to influence the dependent variable. The dependent variable is what happens as a result of the independent variable. A control variable is one that is held constant or finite in a research study. In a controlled experiment, all variables except the independent variables are controlled or held constant so as not to affect the dependent variable. A hypothesis is a proposed explanation for a phenomenon.
<h3>Why are hypotheses important in research?</h3>
- A hypothesis is an idea put forward for the purpose of discussion, that can be tested to see if it is true.
- Hypotheses not only allow researchers to discover relationships between variables, but they can also predict relationships based on theoretical guidelines and empirical evidence.
- Hypothesis formulation requires a thorough understanding of the research topic and a comprehensive review of the previous literature.
<h3>How do you identify your hypothesis?</h3>
Step 1: State your null and alternative hypotheses.
Step 2: Collect data.
Step 3: Conduct statistical tests.
Step 4: Decide whether to reject the null hypothesis.
