Q
Definition of Rigor
A
(Qualitative) (a judgement call) achieving a balance between emic and etic points of view. Trustworthiness of the ethical and credibility of both quantitative and qualitative researches.
25
Definition of Validity
Validity refers to how well a test measures what it is purported to measure.
26
Definition of Reliability
quantitative) This is usually has to do with HOW the data were collected (data is plural by the way and so if you want to be a really cool research nerd you’ll remember that fact!)
27
Definition of Credibility
(qualitative) – establishes that the results of qualitative research are credible or believable from the perspective of the participant in the research.
28
Qualitative Research design types-
* Descriptive exploratory
* Phenomenology-what is the lived experience? What is the meaning? What is the quality?
* Grounded theory- examines processes, inter relationships, interviews, examinations, focuses on social processes and meaning.
* Ethnography-understanding culture of a group, usually about patterns of behaviour within social context of a sub culture
* Historical- document events.
29
Quantitative Research Designs
* Critique – is this article going to answer the research question
* Experimental –quasi experimental.
* Non-experimental- descriptive- correlational
* Descriptive design-
30
What does descriptive statistics allow?
Allows the researchers to describe, organise and summarise raw data
31
What does inferential statistics allow for?
It allows researchers to estimate how reliably they can predictions and generalise their findings based on the data
32
What are the 3 most common measures of variability?
- range
- variance
- standard deviation
33
What is standard deviation?
Standard deviation is the square root of the variance- therefore in same units as original measurements
34
What are the advantages of standard deviation?
- takes all the scores into account
- can be used to interpret individual scores
- standard deviation allows the reader to get a feel for the variation the data contain
- used in calculation of many inferential statistics
35
What are inferential statistics?
It allows inferences or conclusions to be drawn from data
36
What does descriptive statistics do?
It summarises data
37
There are usually 2 purposes for inferential statistics. What were they?
- estimate how well a sample statistic reflects the population parameter
- test hypotheses or predictions about population
38
What do research hypotheses do?
Shows that there is some specified relationship between dependent and independent variables
39
What does a null hypotheses do?
Shows that there is no relationship between dependent and independent variables.
It is easier to disprove something than to prove it.
40
How is trustworthiness/rigor assured in qualitative research?
-Credibility (truthfulness)
-Auditability (consistency)
-Transferability (fittingness/applicability)
-Confirmability (no bias or distortion)
through member checking, audit trails, triangulation
41

applying in clinical practice
42

Research in which the investigator collects and analyses data, integrates the findings and draws inferences using both qualitative and quantitative approaches or methods in a single study.
46
Why conduct mixed methods research?
Seeking convergence and corroboration of results from different methods that are studying same phenomena
47
