FOOD FOR THOUGHT

2. WHAT IS VALIDITY IN RESEARCH?
“Validity can be defined as the best available approximate to
the truth of a given proposition, inference, or conclusion.”
Trochim, William M.K. (2006). Introduction to Validity. In The Research Methods Knowledge Base (pp. 20-30). Ohio: Cengage Learning.

3. CONCLUSION VALIDITY
CASE STUDY: BREAD
Is there a relationship between the
cause and the effect?
Bautista-Castaño, Inmaculada, and Serra-Majem, Lluis (2012). Relationship
between bread consumption, body weight, and abdominal fat distribution:
evidence from epidemiological studies. Nutrition Reviews 70(4), 218-233.

4. INTERNAL VALIDITY
CASE STUDY: TOMATOES
Is the relationship causal?
Agarwal, Sanjiv, and Rao, A. Venketeshwer (1998). Tomato Lycopene and Low
Density Lipoprotein Oxidation: A Human Dietary Intervention Study. Lipids,
33(10), 981-984.

5. CONSTRUCT VALIDITY
CASE STUDY: BEEF
Can we generalize to
the constructs?

Online Library 28(2), 157-172.

6. EXTERNAL VALIDITY
CASE STUDY: CONSUMPTION
Can we generalize to other
persons, places, or times?

7. VALIDITY ADDS UP
THE CUMULATIVE EFFECT
Each type of validity builds on the
one before it.

9. WHAT ABOUT ETHICS IN RESEARCH?
“Ethical norms [for conduct] serve the aims or goals of
research and apply to people who conduct scientific research
or other scholarly or creative activities.”
