PSYC*2360 Chapter 2: The Research Process Flashcards
A process in which the experimenter uses direct and indirect observations or experiences to test a research question is known as what type of approach?
An empirical approach
What must be possible to empirically approach answering a question?
It must be possible to make systematic observations
T or F: Not everything being studied is directly observable, so some level of inference is needed.
True
Once an interesting and empirical research question has been determined, what is the next step?
To see what others have already learned about the topic
What is the best source for finding quality information about a question?
Peer-reviewed journal articles
What is the process by which scientific experts in the field review and evaluate the quality of research before publication?
Peer review
Prior to publication in a research journal, what must be done to a paper?
It must go through the peer-review process
What are research reports/ research articles?
A description of an empirical research study, including how data was collected, analyzed, and interpreted
What are systematic reviews
A review of literature that synthesizes the research evidence on a topic
What are meta-analyses?
A statistical analysis that compares and combines results from multiple studies on the same topic
What is a hypothesis?
An educated guess that provides a testable explanation of a phenomenon
What is the difference between a one-tailed hypothesis and a two-tailed hypothesis?
- One-tailed: Makes a prediction about the direction of results
- Two-tailed: Does not make predictions concerning the direction of results
When a large body of empirical evidence supports a hypothesis, what may that hypothesis eventually become?
A scientific law or theory
What is the main difference between a scientific law and a scientific theory?
- Scientific law: Describes some aspect of the world, but makes no assumptions about why it occurs
- Scientific theory: Provides an explanation for some aspect of the world
What are four strategies for generating a good hypothesis?
FICC:
- Find the exception to the rule
- Introspection
- Consider matters of degree
- Change the directionality
What are four characteristics of a good hypothesis?
FPSH:
- Falsifiability
- Parsimony
- Specificity
- High correspondence with reality
What does the principle of parsimony/specificity suggest?
When there are multiple ways of stating something, the most simple and direct way is best
Occam’s razor refers to what?
Cutting away of the unnecessary
