Answer 2

Conditions of testing
Interpretations
Standardisation
Sample

Question 3

What are conditions of testing?

Answer 3

Is there anything in the environment that will affect participants

Question 4

What does interpretation refer to?

Answer 4

How participants interperet different questions/behaviour (are there any inconsistency)

Question 5

What is standardisation?

Answer 5

Are all participants doing the same thing?

Question 6

How does sample impact reliability?

Answer 6

Potential impact of participant variables

Question 7

What is external reliability?

Answer 7

does the method produce the same results each time the test is carried out

Question 8

What is the test retest method?

Answer 8

Administering the same test twice to see if the same results are obtained

Question 9

What is inter rater reliability?

Answer 9

Two researchers will observe the behaviour independantly and compare data after

Question 10

What is internal reliability often assosiated with?

Answer 10

measures such as attitude scales or personality tests

Question 11

What is the split half method?

Answer 11

Splitting a test into two having the same participant do both halves

Question 12

What makes a test valid?

Answer 12

If it measures what it claims to measure

Question 13

What is internal validity?

Answer 13

Whether a studys results were really due to the variables the researcher suggest were tested by their methodology

Question 14

What is external validity?

Answer 14

The extent to which the results of a study can be generalised beyond the study

Question 15

What is population validity?

Answer 15

Can we generalise from this sample to a wider group

Question 16

What is ecological validity?

Answer 16

Can we generalise from the set of environmental conditions created by the researcher to other environmental to other environmental conditions

Question 17

What is experimenter bias?

Answer 17

Experimenters personal views influence evaluation

Question 18

What are individual differences?

Answer 18

Key aspects of a persons life outside the experiment that can influence results

Question 19

What are order effects?

Answer 19

The order in which the tasks are carried out skew results

Question 20

What are demand characteristics?

Answer 20

When participants alter their behaviour based onn what they think the researcher wants

Question 21

What is face validity?

Answer 21

Does something look like it will measure what it is supposed to measure

Question 22

What is construct validity?

Answer 22

Do the measures relate to the assumed characteristics of what is being assesed

Question 23

What is concurrent validity?

Answer 23

When a test correlates well with a measure that has previously been validated

Question 24

What is criterion validity?

Answer 24

The extent to which a measure can predict the performance or behaviour of the measured thing

Question 25

What is external validity?

Answer 25

Whether the findings of the study can be generalised beyond the context of the study

Question 26

What is population validity?

Answer 26

The extent to which findings can be generalised to other populations of people

Question 27

What is ecological validity?

Answer 27

The extent to which the findings can be generalised beyond the present situation
