Question 1

Hypothesis

Answer 1

Predicts what we expect to find
The idea is to try to find evidence to support your hypothesis

Question 2

Two types of hypotheses

Answer 2

Directional and non directional

Question 3

Directional hypothesis

Answer 3

Predicts a direction for the results
Stress makes memory worse

Question 4

Non directional hypothesis

Answer 4

Does not predict direction simply stated stress will affect memory

Question 5

One tailed

Answer 5

Directional hypothesis

Question 6

Two tailed

Answer 6

Non directional

Question 7

Why is directional hypothesis chosen

Answer 7

When the researcher is confident enough to make clear prediction

Question 8

Why is non directional hypothesis chosen

Answer 8

When researcher is not terribly clear what will happen
Perhaps carrying out study that has not be done before

Question 9

Independent variable

Answer 9

Manipulated in order to see what effect this has

Question 10

Dependant variable

Answer 10

Being measured
Depends on IV

Question 11

Co variables

Answer 11

Used in correlational research
They differ from IV and DV because they both vary and they are both measured
Never set or manipulated

Question 12

Operationalising variable

Answer 12

Means making them measurable
Important as we need to make it clear what we’re studying and measuring

Question 13

Extraneous variables

Answer 13

Something we haven’t controlled for that could affect our DV
Can affect our results
Temp, time of day, noise

Question 14

Co founding variables

Answer 14

Interferes with the relationship between two variables we want to study and can lead us to an incorrect conclusion
