Experimental Designs

Question 1

What is the definition of experimental designs?

Answer 1

How participants are arranged in relation to the different experimental conditions

Question 2

What is an independent group design?

Answer 2

When two separate groups of participants experienced two different conditions of the experiment

Question 3

Advantages of independent groups/measures

Answer 3

Participants are less likely to guess the aim of the study
No order effects -meaning participants don’t get fatigued or bored and perform worse in the second task however they also don’t get more practice and become better in the second condition.

Question 4

Independent group/measures disadvantages

Answer 4

There may be differences between the two group groups of people
Examples such as intelligence

Question 5

What is repeated measures?

Answer 5

One group of participants complete both conditions of the experiment

Question 6

What are an advantage of repeated measures?

Answer 6

There’s no participant variables between the conditions
And fewer participants

Question 7

Disadvantage of repeated measures

Answer 7

There are order effects- however can be addressed by counter balancing-1/2 do 1 first then do condition 2 where as the other 1/2 do condition 2 first then condition 1

Question 8

What are match pairs?

Answer 8

Independent groups, but participants are matched on qualities relevant to experiment
Examples, age IQ and occupations

Question 9

An advantage of much pairs

Answer 9

Order effects and demand characteristics are less likely
Less likely to predict the aim of the study

Question 10

Disadvantage of match pairs

Answer 10

Participants can never be much perfectly is there will still be some different variables
Time consuming and expensive to use this design
