Experimental Research Questions
The role of hypothesis testing in experimental research is to determine whether the observed results of an experiment are statistically significant and can be attributed to the independent variable being tested. Hypothesis testing helps researchers make conclusions about the relationship between variables and provides evidence to support or reject the research hypothesis. It involves formulating a null hypothesis, which assumes no relationship between variables, and an alternative hypothesis, which suggests a relationship exists. Through statistical analysis, researchers can determine the likelihood of obtaining the observed results if the null hypothesis were true, and if the likelihood is sufficiently low, they can reject the null hypothesis in favor of the alternative hypothesis. Hypothesis testing is crucial in experimental research as it allows researchers to draw valid and reliable conclusions from their findings.
