Hypothesis Testing and Null vs. Alternative Hypotheses

A hypothesis is a prediction about a study's outcome, guiding research direction. Stating hypotheses forces deep thinking and making specific predictions but may introduce bias. Null hypothesis (H0) states no effect, while alternative hypothesis (Ha) claims an effect in the population. Researchers e
