Which of the following would help to improve the 'ecological validity' of an experiment?
Doing the experiment at the normal time of day for that activity
Doing the experiment in a different room to normal
Doing the experiment in controlled conditions
Doing the experiment with everyone all at the same time
What does using 'counterbalancing' in an experiment help to prevent?
Order effect
Participant variables
Demand characteristics
Bias
Tick ALL the following types of experimental design which DO NOT provide order effects:
Independent groups
Matched pairs
Repeated measures
Which of the following is a disadvantage of 'matched pairs'?
There will be order effects
There will be a high level of participant variables
It is difficult to match participants exactly
There may be demand characteristics
Which 'experimental design' produces the highest amount of participant variables?
Independent groups
Matched pairs
Repeated measures
Which 'experimental design' does this picture show?
Independent groups
Repeated measures
Matched pairs
Please tick ALL the statements below that refer to 'opportunity sampling':
It is quick and easy to produce
The sample is likely to be very biased
The sample is not likely to be representative
The sample will always contain a mix of genders
Please tick ALL of the statements that are true for systematic sampling:
The sample avoids researcher bias
The sample will be representative
The sample is created by choosing every nth person from a list
The sample always produces an equal amount of each gender
Please tick ALL of the statements that are true for stratified sampling:
The sample avoids researcher bias
The sample is likely to be representative
The sample involves selecting participants from each sub group of the target population
The sample is quick and easy to create
Please tick ALL of the statements that are true for random sampling:
The sample avoids researcher bias
The sample is likely to be representative
The sample can be created using a digital selector
The sample will always contain an equal amount of each gender

Confounding variable
Which variable within an experiment is the one that is measured?
Independent variable
Dependent variable

Which variable within an experiment is the one that needs to be controlled so that it doesn't accidentally affect the results?
Independent variable
Dependent variable
Extraneous variable
Confounding variable
In an experiment that looks at the effect of listening to music on learning, tick ALL the boxes that would be relevant extraneous variables that would need to be controlled:
The time of the day that the experiment took place
The style of music that the participants were listening to
The room where the experiment was completed
The nature of the task that had to be completed
"The amount of breakfast you have to eat will have no effect on your level of concentration in the morning".
What type of hypothesis is this?
Null hypothesis
Alternative hypothesis
Directional hypothesis
Non-directional hypothesis
"The amount of sleep you have will improve your level of concentration in the morning".
What type of hypothesis is this?
Null hypothesis
Alternative hypothesis
Directional hypothesis
Non-directional hypothesis
Tick all of the statements below that are true for a 'laboratory experiment'
The experiment takes place in a laboratory
All of the variables are carefully controlled
The results are considered to be very reliable
The results are true to real life situations
Tick all of the statements below that are true for a 'field experiment'
A confederate is usually used
Some of the variables are carefully controlled
The experiment takes place in a natural environment
Demand characteristics are likely present
Tick all of the statements below that are true for a 'natural experiment'
It can take a very long time to achieve the results
Some of the variables are carefully controlled
The experiment takes place in a natural environment
Demand characteristics are unlikely to be present
Which of the following is the correct definition for 'demand characteristics'?
The participants can work out the aim of the experiment and change their behaviour
The participants will perform better in the first condition than the second condition
The participants will request to know everything about everyone involved in the experiment
The participants are very different to those in the other condition
