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
