🎯 What is a Hypothesis?

A hypothesis is a tentative, testable statement about the relationship between two or more variables.

It serves as the backbone of quantitative research, offering direction, clarity, and a roadmap for data collection and analysis.

In simple terms:

👉 A hypothesis tells us what we expect to find.

🧪 Why Hypotheses Matter

✔ Help frame research questions

✔ Guide selection of variables

✔ Define the research design

✔ Enable statistical testing

✔ Clarify relationships among constructs

📚 Types of Hypotheses

Let’s explore the main types of hypotheses used in social science and business research:

---

1. ✅ Null Hypothesis (H₀)

Assumes no relationship or no effect between variables.

Example:

H₀: There is no significant relationship between employee engagement and productivity.

---

2. 🟢 Alternative Hypothesis (H₁ or Hₐ)

Posits the presence of a relationship or effect.

Example:

H₁: Higher employee engagement leads to improved productivity.

📝 These two hypotheses are always tested together in statistical research.

---

3. 📈 Directional Hypothesis

Specifies the direction of the relationship.

Example:

H₁: Students who receive feedback perform better than those who don’t.

(This assumes a positive effect.)

---

4. 📉 Non-directional Hypothesis

Indicates a relationship but not its direction.

Example:

H₁: There is a significant difference in performance between students who receive feedback and those who don’t.

5. 🔁 Associative vs. Causal Hypothesis

Type	Description	Example
Associative	States variables change together	There is a relationship between income and savings
Causal	One variable causes a change in another	Advertising causes an increase in brand recall

---

🧠 Structure of a Good Hypothesis

A good hypothesis should be:

🔹 Clear and specific

🔹 Testable using measurable variables

🔹 Grounded in theory or past research

🔹 Focused and concise

Basic Structure:

If [IV], then [DV], because [theory/rationale].

Example:

If training is increased (IV), then employee productivity (DV) will improve, because training enhances skills and motivation (based on Human Capital Theory).

🛠️ Tips for Writing Strong Hypotheses

✔ Start with a clear research question

✔ Use theory to back your assumptions

✔ Define variables precisely

✔ Avoid vague terms like "good," "bad," or "better"

✔ Ensure the hypothesis is falsifiable (can be tested and rejected)

🧪 Examples from Business & Social Sciences

Research Topic	Hypothesis (H₁)
E-commerce & trust	Trust positively influences online purchase intentions.
Social media & mental health	Excessive use of Instagram is associated with anxiety.
Leadership & employee satisfaction	Transformational leadership increases employee satisfaction.

---

🧠 Practice Time

Try forming a hypothesis from this question:

“Does visual merchandising affect impulse buying in fashion retail?”

💡 Tip: Identify IV (visual merchandising) and DV (impulse buying).
