Lecture 3: Research Process

Question 1

What does disciplinary mean?

Answer 1

• of or relating to a particular field of study

- a branch of a study

Question 2

What does multidisciplinary mean?

Answer 2

combining or involving more than one discipline or field of study

Question 3

What does interdisciplinary mean?

Answer 3

involving two or more academic, scientific, or artistic disciplines

Question 4

What does transdisciplinary mean?

Answer 4

Research is defined as research efforts conducted by investigators from different disciplines working jointly to create new conceptual, theoretical, methodological, and translational innovations that integrate and move beyond discipline-specific approaches to address a common problem.

Question 5

Good questions are…

Answer 5

1) Ones you feel passionate about answering (i.e., they intrigue you!)
2) Are empirical (i.e., you can use observations and measurements to test the question)
• Please brainstorm some examples of both…
• What is an example of a non-empirical question?

Question 6

What is empirical research?

Answer 6

Empirical research is research using empirical evidence. It is a way of gaining knowledge by means of direct and indirect observation or experience. Empiricism values such research more than other kinds. Empirical evidence can be analyzed quantitatively or qualitatively.

Question 7

What is non-empirical research?

Answer 7

Non-empirical research is research that is conducted without data: quantitative data, which is when you analyze numerical data, or qualitative data, which is when you use non-numerical data such as observations and interviews to base claims off of.

Question 8

What is the purpose of background research?

Answer 8

• Help us gain understanding
• Ask better and more specific questions
• Ultimately advance overall knowledge

Question 9

What is a descriptive research?

Answer 9

Descriptive research is used to describe characteristics of a population or phenomenon being studied. It does not answer questions about how/when/why the characteristics occurred.

Question 17

What is a hypothesis?

Answer 17

An educated guess, based on observation, about the causes or outcomes of an event (how variables are related); can be disproven but not proven to be truth

Question 18

What is a theory?

Answer 18

summarizes hypothesis (or group of hypotheses) supported with repeated tests; an “accepted hypothesis”; can be disproven

Question 19

What is are the differences between hypothesis and theory?

Answer 19

possible vs. certainty; substantiated vs. not; limited data vs. lots; specific observation vs. general

Question 20

What are the similarities of hypothesis and theory?

Answer 20

testable, falsifiable

Question 21

What are the reasoning strategies in generating hypothesis?

Answer 21

• inductive reasoning

- deductive reasoning

Question 22

What is inductive reasoning?

Answer 22

• Use specific facts to form a general conclusion
• E.g., gather specific information on your patients symptoms and then form a hypothesis
• E.g., gather facts from past research studies

Question 23

What is deductive reasoning?

Answer 23

• Derive a hypothesis from a theory; use a general principle to reach more specific conclusion
• E.g., if you have a stomach ulcer, THEN this additional medical test (e.g., barium swallow) should yield the following result (e.g., ulcer visible on X-ray)

Question 24

What are the strategies in generating hypothesis?

Answer 24

• Introspection
- what would I do? think? feel? Leverage your biases!
• Focus on the exception to the rule
- Virtually no outcome is true 100% of the time
• Matter of degree
- Gray areas; focus on variables in terms of amounts
(quantity, strength, volume, time, etc.)
• Change the direction
- Chicken or the egg?

Question 25

What are the features of a good hypothesis?

Answer 25

* Justifiable and grounded in observations OR theory (inductive or deductive?) * Be testable (or, is it possible to gather all evidence to disconfirm it) * Predict a relationship between two or more variables * Not vague – concepts should be clearly defined and based on sound reasoning

Question 26

Give examples of casual and associative hypothesis

Answer 26

* Causal: Dieting men who are participating in a formal exercise program will have greater weight loss than those who are not * Associative: there is a positive relationship between the amount of exercise and weight loss among men who are dieting

Question 27

Give examples of simple and complex hypothesis

Answer 27

* Simple: Infants born to mothers who had iron- deficiency anemia during pregnancy have lower birth weight than infants born to mothers with normal iron levels * Complex: Infants born to mothers who had iron- deficiency anemia during pregnancy have lower birth weight, are at increased risk of pre-term delivery, and have more neurological complications than infants born to mothers with normal iron levels

Question 28

Give examples of directionality hypothesis

Answer 28

* The incidence of decubitus ulcers (bed sore) is related to the frequency of turning patients * Patients turned at least every two hours have a lower incidence of decubitus ulcers than patients turned less frequently

Question 29

Give examples of null hypothesis

Answer 29

* There is no relationship between gender and knowledge of the food pyramid among teenagers * Teenage girls are better informed about the food pyramid than teenage boys
