Principles Of Research Definitions

Question 1

Define the term probability value

Answer 1

• the numerical value that gives indication of the likelihood that results are due to a real difference/ correlation
• aren’t due to chance factors

Question 2

Define sampling frame

Answer 2

• a list to specify the population of interest/ pts who are available

Question 3

Aim of research

Answer 3

Broad statement of the purpose of the research - not as specific as the hypothesis

Question 4

Why would 0.5 be better than 0.01

Answer 4

• 0.05 is less stringent whereas using 0.01 would be less stringent.
• Using 0.05 suggests there’s 5% chance of our results being due to chance whereas using 0.01 would lower this to a 1% chance which may be too strict

Question 5

Confounding variables

Answer 5

Variables

Question 6

Split half reliability

Answer 6

where a test is split in two and the scores for each half of the test is compared with one another. If consistent, internal reliability is high; if not, it is low and individual questions would need to be re-ordered or redesigned to improve reliability.
