Question 2. The scientific method and measurement concepts
The scientific method is characterised by an empirical approach. Key concepts
include clear conceptual and operational definitions of constructs, reliable and valid
measures, and testable hypotheses.

Complete the following:
(a) Choose two psychological concepts that you think could be related
(correlated) to each other e.g., boredom and social media use (Do not use
this example yourself!). Provide a conceptual definition for each concept and
write a brief rationale that describes why you think the two variables might be
related. State a hypothesis that flows from your rationale and includes both
constructs. (4 marks)

(b) Provide an operational definition for the constructs you chose in (a). How
would you measure these variables? (You can use established measures)
(2 marks)

(c) Differentiate between the reliability and validity of a measure. Using the
operational definitions you provided in discuss:
i) two methods for determining reliability (2 marks)
ii) two methods for determining validity (2 mar
