Aims and Hypothesis

Question 1

Null hypothesis

Answer 1

There is no relationship between the two variables being studied

Results are due to chance and are not significant in terms of supporting the idea being investigated

Question 2

Alternative hypothesis

Answer 2

The hypothesis states there is a correlation between two variables

Results not due to chance

Question 3

Non directional hypothesis

Answer 3

The independent variable will have an effect on the dependent variable, but the direction of the effect is not specified

e.g there will be a difference in how many numbers are correctly recalled by children and adults

Question 4

Directional hypothesis

Answer 4

One tailed
Predicts the nature of the effect of the independent variable on the dependent variable

e.g adults will correctly recall more words than children

Question 5

Aim

Answer 5

What the researcher intends to investigate, the purpose of the study

Question 6

Hypothesis

Answer 6

A clear precise testable statement that states the relationship between the variables to be investigated

Question 7

Operationalisation

Answer 7

Clearly defining variables in terms of how they can be measured
