Question 1 Report
A café owner changes the position of a donation jar each week to examine decision-making behaviour. At the counter, the jar is placed beside either a photograph of local patients, a graph showing fundraising progress, or no prompt. The owner records daily donations but also notes weather and customer numbers.
(a) Identify the independent variable. [1]
(b) Describe why customer number should be considered when interpreting the donation results. [2]
Answer Details
(a) The donation prompt beside the jar: patient photograph, fundraising graph or no prompt [1] (b) More customers provide more opportunities to donate [1]; therefore a higher total may be due to customer numbers rather than the prompt's effect on decision-making behaviour [1]. [2]
