Research Methods

Question 1

What is a Non directional hypothesis

Answer 1

A prediction which states that there will be a difference between conditions or that there will be a correlation but which does not state which direction the difference will go in

Question 2

What is a directional hypothesis?

Answer 2

A prediction which states the direction of the differences between two conditions or which states the direction of any correlation between two variables

Question 3

What is independent groups experimental design?

Answer 3

Different participant in each condition of the iv.

Question 4

Give a strength of independent groups

Answer 4

There is no chance of learning/improvement (practice effects) between the first time they do the experiment and the second time.

Question 5

What is a weakness of independent groups?

Answer 5

There may be differences between the people in the groups - participant variables

Question 6

What is repeated measures experimental design?

Answer 6

Each participant does both conditions of the independent variable

Question 7

Give a strength of repeated measures

Answer 7

It controls differences between participants’s

Requires less participants

Question 8

What is a weakness of repeated measures?

Answer 8

It takes longer

There may be order effects - may be better because of practice

Question 9

What is matched pairs experimental design?

Answer 9

Each person only does one condition of the independent variable

Question 10

What is a directional (one tailed) hypothesise?

Answer 10

States the direction of difference between two conditions
