Lab experiment

Answer 1

Uses a highly controlled and standardised setting to manipulate iv and measure dv

Question 2

Feild experiment

Answer 2

Iv is manipulated and dv is measured in a real world setting

Question 3

Natural experiment

Answer 3

A research that occurs in the participants natural setting that has no manipulation by researcher

Question 4

Quasi experiment

Answer 4

Have an iv that is based on existing differences between people e.g someome with ocd and someome without

Question 5

Dependant variable

Answer 5

Measured

Question 6

Independent variable
Iv

Answer 6

Something that is changed

Question 7

Extraneous variable

Answer 7

Any variable that your not investigating that can potentially affect the outcome of your research study

Question 8

Reliability

Answer 8

Consistent findings in the results

Question 9

Demand characteristics

Answer 9

Cues that can change how the participants behaviour

Question 10

Standardised procedure

Answer 10

procedures used in researches are kept the same

Question 11

Standardised

Answer 11

Easier to replicate

Question 12

Reliability

Answer 12

Consistancy

Question 13

Inter observer reliability

Answer 13

No consistency between observers
(observing different things)

Question 14

Questionaire

Answer 14

Ps fill out themselves when handed out to them

Question 15

Structured interview

Answer 15

Pre determined question

Question 16

Unstructured interview

Answer 16

No predetermined questions
Can go off On a tangent

Question 17

Open question

Answer 17

Ps can express themselves and give researcher a fuller understanding

Question 18

Closed question

Answer 18

Easy to analyse and draw conclusions
Limited answers only

Question 19

Repeated measure design

Answer 19

P’s tested in one condition then tested in another condition

Question 20

Independent group design

Answer 20

P’s split into number of groups needed and undergo one condition of the study

Question 21

Matched pair designs

Answer 21

2p’s in a pair with similar variables and one person from each pair will experience a different condition of the study

Question 22

Directional hypothesis

Answer 22

Aware of any past research
Predict way results will go
Uses words like faster slower more less

Question 23

Non directional hypothesis

Answer 23

Unaware of past research
Don’t know which way research will go
Uses words such as difference

Question 24

Opportunity sampling

Answer 24

Asking who is most available at time to participate

Question 25

Self selecting sampling

Answer 25

Advertising for voluteers so they sign up them selves

Question 26

Systematic sampling

Answer 26

Nth sampling Selecting every 20th person after simplifying the group number

Question 27

Random sampling

Participants picked out of a hat or spiny wheel

Question 28

Stratified sampling

Answer 28

Target population relevant to research Decide strata(gender,age) Take random sample from strata

Question 29

Counter balancing ( aba)

Answer 29

Used in repeated measure Participants do condition one then condition b and other participants do condition b then condition a

Question 30

Single blind procedure

Answer 30

Participants not told aim

Question 31

Double blind procedure

Answer 31

Researcher nor participant know the aim

Question 32

What does Random allocation do

Answer 32

Used in independant grouo design Ensures everyone has equal chance

Question 33

Experimental designs are about

Answer 33

How participants are allocated to conditions of the iv

Question 34

Order effects consist of

Answer 34

Practice, fatigued and boredom

Question 35

2 reason why it’s appropriate to use sign test

Answer 35

Differences between 2 sets of data Data is nominal and can be put in catagories

Question 36

Answer 36

Variables are defined and can easily be measured

Question 37

Operationalise aggression in a playground

Answer 37

Measure the frequency of agressive acts such as hitting and shouting in a playground

Question 38

2 reasons why conducting a peer review can improve research

Answer 38

Mega anlaysis to examine for errors and inconsistency Ensuring research adheres for ethical guidelines
