Hypotheses, Operationalisation and Experimental Types

Question 1

One tail hypothesis

Answer 1

• A hypothesis that states one condition will better than the other

Question 2

Two tail hypothesis

Answer 2

• A hypothesis that just states that there will a difference between condition

Question 3

Null hypothesis

Answer 3

• A statement that there will be no difference between groups

Question 4

• What is a sample?

Answer 4

• Is a small portion of participants you get from the wider population. Generally you want your participants to represent your population

Question 5

What is a population?

Answer 5

• Is the target group which you want your research to be able to explain their behaviour

Question 6

What is sampling methods?

Answer 6

• The ways that you can get a sample from your population

Question 7

Opportunity sampling

Answer 7

• Collecting your sample by convenience sampling
• Done by finding people who are in immediate vicinity or easiest to get involved in your research

Question 8

What is a lab experiment?

Answer 8

• A experiment that takes place in a very controlled enviroment

Question 9

What is a field experiment>

Answer 9

• Takes place in an everyday surrounding

Question 10

Strengths of lab experiment

Answer 10

• It is easier to replicate and it is a standardized procedure

Question 11

Weakness of lab experiment

Answer 11

• The artificiality of the setting may produce unnatural behaviour that does not reflect real life. This means it would not be possible to generalize the finding to a real-life setting

Question 12

Strengths of field experiment

Answer 12

• Behaviour in a field experiment is more likely to reflect real life because of its natural setting
• Less likelihood of demand characteristics affecting the results as the participants may not know they are being studied

Question 13

Weakness of field experiment

Answer 13

• There is less control over extraneous variables that might bias the results and this makes it harder for other researchers to replicate

Question 14

Independent groups design

Answer 14

• When different groups are assigned to different IV conditions
• They might take part in the experimental group or a control group

Question 15

Repeated measures design

Answer 15

• When the same group goes through every experimental condition

Question 16

Matched pair designs

Answer 16

• When participants who are similar in key variables are put into different groups
• Which then are put into different experiment conditions
