Ho

"Ho" can refer to various concepts depending on context, but one common usage is in the context of mathematics, specifically in hypothesis testing. In this setting, "Ho" stands for the null hypothesis, which is a statement that there is no effect or no difference in a given situation. Researchers test this hypothesis to determine if evidence exists to support an alternative hypothesis (often denoted as "Ha"), suggesting that there is an effect or difference. The null hypothesis acts as a starting point for statistical analysis, guiding researchers in their conclusions based on their data.
