Iv
The thing that changes
Dv
The thing you measure
Cv
The things that stay the same
Order effect
Occurs when the participants performance in the second condition is affected because they have already done the first condition.
They may do better or worse because of the practice, this may happen in a repeated measure design.
Participant variables
Differences between the people who take part in the experiment. These may affect the results of an experiment that uses an independent groups design
Standardised procedures
A set order of carrying out a study that is applied to all participants when necessary
Counter balancing
A procedure for evening out the order in which participants complete both conditions of an experiment
Randomisation
Using chance to produce an Order for a procedure
Participant
Person selected to take part In a study
Sample
A small group of people who represent the target population and who are studied
Target population
The large group of people the researcher wishes to study
Generalised
The results from the sample can be said to apply to the target population
Random sample
Ever member of target population has an equal chance of being selected for the sample
Opportunity sample
People who are members of the target population and are available and willing to take part
Systematic sampling
Ever nth member of the target population is selected for the sample
Stratified sample
To obtain this type of sample the different subgroups in the target population are identified then people are randomly selected from these subgroups in proportion to their numbers in the target population
Mean average
Statistic calculated by adding all the scores In a set of vaulue sand dividing the total by the number of values in the set
Median
The middle value in a set of values when the values have been arranged in ascending order
Range
The difference between the lowest and Highest values In a set of values
Anomalous result
An extremely high or low result that does not match the other results in a set of scores
Percentage
A proportion expresses as a fraction of 100
