Flashcards in 2 - Research Designs Deck (16):
1

nomothetic

an explanation should apply to humanity in general, not just to the people who participated in the study

2

three criteria of causation

correlation, time order, non-spuriousness

3

what does it mean that nomothetic explanations need to correlate?

the proposed cause and the proposed effect have to vary together

4

what does it mean that nomothetic explanations need to satisfy time order

the proposed cause must precede the effect in time

5

what does it mean that nomothetic explanations need to be non-spurious

alternative explanations for the correlation observed have to be ruled out

6

measurement or construct validity

refers to whether a particular indicator actually does measure what it is supposed to measure, applies primarily to quantitative research. ex: IQ

7

internal validity

causality

8

external validity

whether a study's finding are applicable in settings outside the research environment, and whether the results of a study can be generalized beyond the people or cases analyzed by the researcher

9

which one is more likely to be externally valid: qualitative or quantitative?

qualitative, because it usually takes a naturalistic stance

10

naturalism

a style of research that seeks to minimize the use of artificial methods of data collection

11

cross sectional vs longitudinal

one point in time vs across time

12

types of case studies

critical, extreme/unique, revelatory

13

critical case

the researcher has a clearly specified hypothesis, and a case is chosen on the grounds that it will allow a better understanding of the circumstances under which the hypothesis does or does not hold

14

extreme/unique case

common focus in clinical studies

15

revelatory case

when an investigator has an opportunity to observe and analyze a phenomenon previously inaccessible to scientific investigation

16

what kind of validity do case studies often lack?

external validity
