Definition
- The presumed effect
- A statement which predicts the relationship between the variables that are to be measured during a study
- When the findings are distorted
- When either the researcher or the participant does not know which intervention or treatment the participant has received
- Enable extrapolations to be drawn to the wider population
- A small scale version of the larger planned study
- A sampling strategy which means that potential participants have an equal or random chance of being invited to take part
- Participants who receive the conventional (usual) or placebo intervention in a randomised controlled trial
- When the researcher and the participant do not know which intervention or treatment that the participant has received
- The middle value when all the scores or cases are placed in order
- Testing a theory or hypothesis
- Application of the findings to the wider population
- Measures of central tendency
- A mock or dummy treatment
- The presumed cause that causes the effect
- The most commonly occurring score or case
- Link or association
