Chapter 2 (engels): Research ideas and hypotheses

Question 1

Literature search

Answer 1

To find an idea for study that gives a general statement ab the relation between two variables

Question 2

Characteristics of a good hypothesis

Answer 2

Logical, testable, refutable and positive

Question 3

A logical hypothesis

Answer 3

• A logical conclusion(=Hypothesis) of a logical argument
• Logical argument provides a rationale or justification for hypothesis and establishes a connection between your research and the research results that have been obtained by others

Question 4

A Testable hypothesis

Answer 4

• A hypothesis where all the variables can, events, and individuals can be testes and observed
• Possible to measure everything involved
• Must be real situations, real events, and real individuals

Question 5

A refutable hypothesis

Answer 5

• Refutable= possible to obtain research results that are contrary to the hypothesis
• science research must be appropriate for objective and subjective demonstration
• ex. If people could fly, there would be fewer depression cases -> can’t be proven!!!

Question 6

a positive hypothesis

Answer 6

• Must be a positive statement about an existence of something (relationship, treatment, …)
• Prediction that denies existence is untestable
• Based on scientific process used to test prediction
• Hypothesis that denies existence cannot be tested in a research study -> not a good foundation

Question 7

Using a hypothesis to create a research study

Answer 7

• Transform general hypothesis into a specific research study
• Hypothesis converted in a research prediction that can be verified or refuted
• General hypothesis can be transformed in several different research studies
  –> You can use a general hypothesis from an already existing study and develop own study
