what is the eight types of hypothesis in scientific method
Answer (1)
8 Types of Hypothesis1. Null Hypothesis (H₀)A statement that there is no effect or relationship between variables.Example: “There is no difference in plant growth between sunlight and shade.”2. Alternative Hypothesis (H₁ or Ha)A claim that contradicts the null hypothesis; shows there is an effect or relationship.Example: “Plants grow taller in sunlight than in shade.”3. Directional HypothesisPredicts the specific direction of the relationship (e.g., increase or decrease).Example: “Students who sleep more will perform better on tests.”4. Non-Directional HypothesisSuggests a difference exists, but doesn’t state which way.Example: “There is a difference in test scores between students who sleep more and those who don’t.”5. Simple HypothesisShows a relationship between one independent and one dependent variable.Example: “More study time improves exam scores.”6. Complex HypothesisInvolves two or more independent/dependent variables.Example: “Diet and exercise affect weight and energy levels.”7. Associative HypothesisStates that variables change together, but not necessarily one causing the other.Example: “There is a link between stress levels and sleep quality.”8. Causal HypothesisClaims that one variable causes a change in another.Example: “Drinking caffeine causes increased alertness.”
