Lesson 5- Aims & Hypotheses

Question 1

What is an aim and what should it include?

Answer 1

Aims- precise statement about purpose of study & what it intends to find out
- Should include what is being studied & what the study is trying to achieve

Question 2

What is the operationalisation of variables?

Answer 2

Operationalisation of Variables- operationalise IV & DV (define variables & say how to measure them)

Question 3

What is a hypothesis?

Answer 3

Hypothesis- precise, testable statement about expected outcome of investigation

Question 4

Give an example of a operationalised hypothesis using chocolate 🍫 and mood as an example

Answer 4

Eating 250g milk 🍫 means pps significantly ⬆️ likely score between 7-10 on mood scale than 1-10 than if they have ✖️ consumed 🍫

Question 5

What are the 2 types of hypothesis’?

Answer 5

1) Null hypothesis

2) Alternate hypothesis

Question 6

What are the 2 types of alternate hypothesis?

Answer 6

1) Non-directional (2 tailed)

2) Directional (1 tailed)

Question 7

What is a null hypothesis?

Answer 7

Null Hypothesis- IV will have no effect on DV (e.g. ‘eating chocolate will have no significant effect on a person’s mood’)

Question 8

What is an alternate hypothesis?

Answer 8

Alternative Hypothesis- IV will have an effect on the DV (e.g. Chocolate will have an effect on mood)

Question 9

What is a non-directional hypothesis?

Answer 9

Non-Directional Hypothesis (2 tailed)- does ✖️ state direction (e.g. ‘eating chocolate will significantly affect a person’s mood’)

Question 10

What is a directional hypothesis?

Answer 10

Directional Hypothesis (1 tailed)- states direction (e.g. ‘eating chocolate will ⬆️ a person’s mood’)
