week 2 Flashcards
(53 cards)
define popualtion
when all the members of a group are surveyed (e.g., all OTs in Victoria; all parents of 5 year old children in Frankston; all patients admitted to a rural hospital ER in 2017).
define sample
subgroup / subsample of a population who are surveyed; is the part of the population that one uses to administer a survey & collect information.
define concept
an abstraction formed by generalisations from similar phenomena or similar attributes.
define construct
is a concept that is systematically defined to be used in scientific theory
types of survey questions
1) Those that ask about behaviors or facts
- Non-threatening behavior questions
- Threatening behavior questions
- Demographics
2) Those that ask about psychological states or attitudes
3) Those that ask about knowledge
What is a good question?: Summary Points
- One that yields a truthful, accurate answer
- One that asks for one answer on one dimension
- One that accommodates all possible contingencies of response
- One that uses specific, simple language
- One that has mutually exclusive response options
- One that produces variability in response
- One that minimises social desirability
- One that is pre-tested
steps that a researcher might consider when dealing with highly sensiittvie survey material
- Minimise a sense of a judgment.
- Maximise the importance of accuracy.
- Use self-administered data collection procedures.
- Ensure confidentiality & anonymity
Five types of closed-ended questions
1) Likert-scale
2) Multiple-choice
3) Ordinal
4) Categorical
5) Numerical
Advantages of open ended questions:
- Allows researcher to obtain answers that were not anticipated.
- May describe more closely the real views of respondents.
- Respondents like the opportunity to answer questions in their own words.
- Are appropriate when the list of possible answers is longer than is feasible to present to respondents.
Advantages of closed questions:
- Respondents can more reliably answer questions when the response alternatives are provided.
- Researcher can more reliably interpret the meaning of answers when they are provided.
- Avoids the context where respondents will provide rare answers that are not analytically useful.
- Ensures a conformity and consistency of respondents’ answers to questions.
3 types of measures
- Nominal: people / events are sorted into unordered categories
- Ordinal: people / events are ordered or placed in ordered categories along a single dimension.
- Interval data: numbers are attached that provide meaningful information about the distance between ordered stimuli or classes….interval data are rare in survey research.
survey errors
sampling error
coverage error
measurement error
non response error
whats sampling error
- The results of surveying only some, and not all, elements or parts of the population
- The extent to which the precision of the sample survey estimates are limited by the number of persons surveyed
whats coverage error
- The result of not allowing all members of the target survey population to have an equal or known nonzero chance of being sampled for participation in the survey
- When the ‘list’ from which the sample is drawn does not include all elements of the population under consideration
whats measurement error
- Respondents’ answers to the survey questions are inaccurate, imprecise, or cannot be compared in any useful way to other respondents’ answers
- Results from poor wording or phrasing of the survey questions or the overall construction of the questionnaire
whats non response error
- The result of people who respond to a survey being different from sampled individuals who did not respond, in a way that is relevant to the study; non-responders to a survey being fundamentally different that the participants who did complete a survey
- When a significant number of people in the same do not respond AND have different characteristics from those who do respond
multi method research vs mixed methods
Multimethod research designs:
- Single research approach e.g. qualitative or quantitative
- Two or more data collection methods in single study – Qualitative study – known as data triangulation e.g. interview, observations – Quantitative study – e.g. survey with study participant and a survey completed by carer (proxy report)
VS
Mixed methods research design
- Quantitative & qualitative approach used in single study
- Concurrent or Sequential design
mixed methods benifits
- broadens the scope of study
- answer complex research questions
- brings together qual and quant
can take multiple approaches
mixed methods challenges
- study takes longer in all phase design
- researcher requires expertise qual and quant research paradigms
3 different approaches to mixed methods research
convergent
explanatory
exploratory
whats convergent parallel mixed methods design
- Qual & quant research traditions equal
- Provides comprehensive analysis of research problem
- Both qual & quant data collected at same time
- Interpretation of results integrated
- May highlight contradictions in qualitative & quantitative findings
whats explanatory sequential mixed methods design
- Quantitative 1st to explain relationships follow up with qualitative and iterpretation
whats exploratory sequential mixed methods design
- Qualitative 1st to explore peoples experiences builds to quantitative to interpretation
reliability
Refers to how well the data collected by using a questionnaire can be reproduced. Types: test-retest, internal consistency, intra-rater reliability & inter-rater reliability.
