The Null Hypothesis is a fundamental concept in statistics that proposes there is no significant effect or relationship between variables. It serves as a starting point for statistical testing, suggesting that any observed differences are due to random chance rather than a true effect. Researchers aim to either reject or fail to reject the null hypothesis based on their data analysis. In hypothesis testing, the null hypothesis is often denoted as H0. If the evidence from the data is strong enough, researchers may reject H0 in favor of an alternative hypothesis, which suggests that a significant effect or relationship does exist. This process helps in making informed conclusions based on empirical data.
