1
What does the Independent variable mean
The thing that we are in control of and change
2
What is the dependant variable
Is the thing that we measure the results of the experiments
3
What is operationalisation
When we say how we observe more complex or abstract things such as the intelligence or aggression levels of something
4
What is an alternative hypothesis
Where you make a prediction of how the IV will affect the DV
5
Null hypothesis
This is where you make the prediction that the IV will not affect the DV
6
What are the two types of alternative hypothesis
One tailed and two tailed
7
What is a one tailed hypothesis in comparison to a two tailed hypothesis
A concrete prediction of what will happen whereas two tailed suggests that there will be a change but there isn’t certainty of what it will be
8
What is an extraneous variable
Anything other then the IV which affects the DV
9
what is a lab experiment
standardized procedure
high IV
low EV
10
what is a field experiment
opposite to lab experiment, it is naturalistic
11
what is a case study
indepth look at a person or a small group eg genie
12
what is a covert experiment
person is in the study but doesn't say ie confederate in milgrams study
13
what is an overt experiment
researcher tells participants they are in a controlled experiement
14
difference between participant and non participant
non p= fly on wall
ppt= involved in study
15

17

20
what is a volunteer sample
self selected, those who chose to be there
21
what is an opportunity sample
asking ppts available at the time
22
what are the three types of reserach design
independant measures
repeated measures
matched pairs
23
what is independent measures
different groups for each condition of the independant variable
24
what is repeated measures
same participants each time for each different condition
25
what is matched pairs
participants matched on certain characteristics and put into seperate conditions
26
type 1 error
rejecting null hypothesis
