Design A Study

Question 1

What type of groups were used in the study design?

Answer 1

Independent groups

Independent groups help to reduce order effects.

Question 2

What is the independent variable (IV) in the experiment?

Answer 2

Amount of exercise (30 mins - none)

The IV is manipulated to observe its effect on the dependent variable.

Question 3

What is the dependent variable (DV) in the study?

Answer 3

Level of happiness (scale 1-10)

The DV is measured to assess the impact of the IV.

Question 4

What type of control was implemented in the study?

Answer 4

Type of exercise where exercise took place

Controls help to ensure that the results are due to the IV.

Question 5

What materials were used in the experiment?

Answer 5

• Rating scale
• Questionnaire assessing happiness
• Exercising equipment

These materials are necessary for measuring the outcomes of the study.

Question 6

What statistical methods were used for data analysis?

Answer 6

• Descriptive statistics (median, range)
• Inferential tests (Mann Whitney U test)

Descriptive statistics summarize the data, while inferential tests help determine if results are statistically significant.

Question 7

What is the purpose of the Mann Whitney U test in this study?

Answer 7

To analyze ordinal independent data

The Mann Whitney U test is suitable for comparing differences between two independent groups when the data is ordinal.

Question 8

Fill in the blank: The study aims to investigate whether exercise could increase _______.

Answer 8

Feelings of happiness

Question 9

What should be devised for measuring happiness in the study?

Answer 9

A measure that would provide data suitable for ordinal measurement

This ensures that the measurement aligns with the statistical methods used.
