What is the research/experimental design?
The operarionalisation of the variables
The selection of the studies participants
The allocation of the sample into conditions
The creation of the studies equipment
The controlling of extraneous variables.
What type of design involves splitting participants into groups and testing each in just one condition of the study?
Independent measures design
Repeated measures design
Matched paires design
Research design
Experimental design
What is a weakness of repeated measures design?
Demand characteristics are more likely as participants guess the aim
More participants are needed
It is more time consuming to organise the participants into their conditions
Individual differences between the partipcants may cause the differences in the results.
Some conditions of the study would have different participants so it wouldn't be fair
Which concept is most similar to external validity?
accuracy
consistency
generalisation
replicability
precision
What is an issue of validity concerned with an independent group design?
Participants differ between conditions
The order can affect the outcome of the experiment
The sample that was taken may be biased
It is time consuming to match them, which can tire the researchers
The participants will guess the aim of the study hence demand characteristics
Which of the following is not an example of an investigator effect.
the interviewers appearance makes the participant want to give desirable answers
the interview's tone of voice emphasises the correct answer to a question
the participant guesses the aim of the study and decides to sabotage it
Which of the following is a weakness of matched pair designs?
Participants were randomly allocated
More participants are needed than an independent group design
Time-consuming to match participants
Order effects mean that results may reflect practice
there are no weaknesses
Which method would allow a research to assess the reliability of a piece of research?
replicating the study
hiding the aim of the research
comparing the results with a piece of research with a similar aim
all of the answers
Match the definitionefinition to the sampling method
stratified sampling
dividing the population into subgroups and then taking a random sample from each subgroup
random sampling
selecting individuals by chance, so that each individual has an equal probability of being chosen
volunteer sampling
participants self-select into the sample
opportunity sampling
dividing the population into clusters and then randomly selecting some of those clusters
Bartlett analysed the participant's retelling of the story of the war of the ghost. What type of data did Bartlett analyse?
Qualitative
Quantitative
Numerical
None of the above
An investigator effect could be decreased by ...
single blind study
double blind study
controlling extranous variables
hiding the aim of the study
matched-pair design
In the study of HM, the researcher Milner used several methods, such as interviewing HM, interviewing his family, and observations, to conclude that he had anterograde amnesia. What is this method called?
inter-rater reliability
test-retest method
replication testing
triangulation
An advantage of quatitative data is that is not considered to be (a) , as the statistical results are not open to interpretation. Despite this argument, this type of data is still criticized for being (b) . (c) data to a number is thought to possibly take away some of the (d) of the original behavior being studied.
