Research Process Key Words Flashcards
A design of experimental research design in which the only measurement that takes place is the impact of the experimental and control interventions, which are measured after the manipulation of the independent variable.
After-only design
Post-test only design
A non-probability sampling strategy whereby the researcher recruits the most readily available participants who meet the study’s inclusion criteria.
Convenience sampling
Opportunistic sampling
Accidental sampling
A design of experimental research which involves the collection of dependent variable data before and after the independent variable is introduced
Before and after design
Pre-test, post-test deign
A design of experimental research which involves two separate groups of participants.
Between participant
Literature search operators which allow the inclusion of multiple words and concepts searches.
Boolean operators
A non-probability sampling strategy which involves the identification of potential participants through referrals from earlier participants.
Snowball sampling
Network sampling
Nominated sampling
Chain sampling
An analysis which is directly relevant to patients’s situation.
Clinical effectiveness
A type of probability sampling. The study total population is divided into sub-groups or clusters. The clusters are then selected randomly. Either the whole cluster participants in the study or participant may be randomly selected from the cluster.
Cluster sampling
The outcome measure of a study which has previously been confirmed or established in another study
Construct validity
The extent to which a data collection encompasses all aspects of the variables being measured.
Content validity
A non-experimental research design which involves the collection of data in order to determine links or association between variables.
Correlation design
A term used in the context of qualitative data analysis whereby consideration is given to whether the findings are realistic or believable
Credibility
identifying a study’s strengths, weakness and limitations in an objective and balanced way to determine whether it is valid and reliable or trustworthy.
Critical appraisal
An experimental research design in which participants act as their own control. During the course of the study each participant is exposed to both the experiment and control treatment.
Within-Participant
Repeated measures design
Cross-over design
A non-experimental research design which involves data collection at on point in time from a cross-section of a defined population.
Cross-sectional design
One-hit design
One-shot design
A non-experimental research design which involves a panel of experts recruited with the aim of reaching consensus about the topic under investigation through rounds of data collection.
Delphi design
A non-experimental research design which involves the collection of data retrospectively whereby the dependent variable has already been affected by the independent variable.
After the fact design
Retrospective design
Ex post facto design
The extent to which the findings can be generalised to the total population and other settings
External validity
The extent to which a data collection tool appears to measure what is intended.
Face validity
A non-experimental research design which involves the repeated collection of data at pre-specified intervals from the same sample over a set or on-going period of time.
Longitudinal design
Panel or trend design
Follow-up design
The extent to which other possible explanations of the findings can be excluded.
Internal validity
A non-probability sampling strategy whereby the researcher decides which potential participants to invite to take part in a study.
Purposive sampling
Purposeful sampling
Judgement sampling
Combines probability and non-probability sampling whereby a list is made of all participants in the population. The first participant is selected randomly and from then on every nth participant is selected.
List sampling
Systematic sampling
An experiment design in which participants in the experimental and control groups are matched as closely as possible.
Matched pair design
