G541: Experiments

Question 0

Order effects

Answer 0

•practise 
•bordom
•fatigue 
-errors begin to arise due to order 
ONLY with repeated measure design

Question 1

Field

Answer 1

Natural environment
•high eco validity
•IV is manipulated

Question 2

Operationalising the IV&DV

Answer 2

Making it measurable

Question 3

Confounding Variables

Answer 3

Variables which cannot be controlled as it may be unethical, impractical or impossible (if it’s unknown)

Question 4

Demand characteristics

Answer 4

Pps aware of the aim which can influence their behaviour/ they act in a way to display behaviour which they think is expected of them

Question 5

One tailed hypothesis

Answer 5

There will be a significant increase/decrease in x and y

•directional

Question 6

Do experimental methods manipulate the IV&DV

Answer 6

Yes- to demonstrate a casual relationship

Question 7

Two tailed hypothesis

Answer 7

There will be a significant relationship between X and Y

•but direction is unknown

Question 8

Quasi experiment

Answer 8

Naturally occurring IV

•used to study real life problems

Question 9

Null hypothesis

Answer 9

•predicts that there will be no relationship

There will be no difference in X and Y

Question 10

Repeated Measures Design

Answer 10

Participants take part in both conditions

Question 11

Experimenter Bias

Answer 11

Any cues from the experimenter which may encourage certain behaviours, leading participants to fulfil the experimenters expectations
• experiment is therefore more likely to see results which they’d hoped for

Question 12

Independent measures design

Answer 12

Participants take part in one condition

Question 13

Matched pairs design

Answer 13

Participants are matched on variables e.g age/gender/intelligence in order to reduce the effect of individual differences

Question 14

Extraneous Variables

Answer 14

Anything other than the IV which has an effect on the DV
•situational
•pps variables

Question 15

10 Markers

Answer 15

What? Hypothesis, operationalise
Who? Sample
Where? Environment
Materials? What'll be used to asses DV
How? Technique

Question 16

Lab experiment

Answer 16

High in control, scientific setting

Question 17

What is central tendency?

Answer 17

Eg mean/median/mode

Why are they a good measure to represent the average
