Lecture 8 Flashcards
1
Q
What defines non-experimental research?
A
- research that lacks manipulation of the independent variable
- used when researcher has question about a casual relationship between two variables
2
Q
Two broad categories of non-experimental research
A
- correlational research
- observational research
3
Q
Correlational research
A
- measuring of two variables without controlling extraneous variables then assessing the relationship between them
4
Q
Observational research
A
- making observations of behaviour in a natural or laboratory setting without manipulating anything
5
Q
Pearson’s Correlation Coefficient
A
- ranges from -1 (strongest negative relationship) to +1 (strongest positive relationship
- 0 means no relationship
- only good for linear relationships
6
Q
Two reasons why correlation does not imply causation
A
- directionality problem
- Third-variable problem
7
Q
Factor Analysis
A
- used to study relationships between multiple variables that are very similar to each other
8
Q
Regression
A
- used to make predictions about the value of one variable given the value of another variable
9
Q
Qualitative Research
A
- all the weaknesses in quantitative research are the strengths of qualitative
- provides in-depth info about relatively few people
- conclusions based on interpretations drawn by investigator
10
Q
What is Guba’s Model of Trustworthiness
A
- four factors
- truth value, applicability, consistency, neutrality
11
Q
Techniques for demonstrating credibility
A
Time sampling - interviewing participants at different times of day
Triangulation - Checking results with multiple raters/measures
Member checking - asking test group if results seem applicable or correct
Peer examination
