Abstract: 

Responses of 73 students to an interciew protocol based on selecting 10 lollies from a container with 50 red, 20 yellow, and 30 green are categorised with respect to centre and spread of numerial answers and to reasoning expressed in justification of the answers. Results are compared to earlier survey research and small-scale interview studies.
