Qualitative codebooks

The exploratory qualitative questions in our study were coded in the following ways:

Question	Career goal change	Relationships	Types of change	Expectancy-value variables
Q9.4	✅	N/A	✅	✅
Q9.5	N/A	Statistics attitudes → Career goals	✅	✅
Q9.6	N/A	Career goals → Statistics attitudes	✅	✅

Career goal change

Q9.4 Have your career goals changed since starting your psychology degree? In what way(s)?

Notation	Code	Examples
0	No	“No”, “I still do have the same goal”, “Not really”
1	Yes	“Yes”, “I used to… now…”, “I have become more open”
2	Maybe	“Slightly”, “I have questioned”, “a little”
N/A	Respondent did not answer the question	“N/A”, “I want to have a family first”

Relationships

Q9.5 Do you think that your attitudes towards statistics have influenced your career goals? If so, in what ways?

Q9.6 Do you think that your career goals have influenced your attitudes towards statistics? If so, in what ways?

Notation	Code	Examples
0	No	“No”, “I don’t think…”
1	Yes	“Yes”, “I think so”, or respondent describes how
2	Maybe	“Perhaps”, “maybe”
N/A	Respondent did not answer the question	“N/A”, “I do enjoy statistics…”

Types of change

Q9.4 Have your career goals changed since starting your psychology degree? In what way(s)?

Notation	Code	Examples
1	Reevaluate existing goals	“I used to want to… now…”, “I’m no longer sure”, “Since learning R, I have…”
2	Opened up more options	“I realised there are a lot more roles/options”, “Found interest areas”
3	Reaffirmed existing goals	“I still have this goal”, “It had always been my goal”
4	Narrowed down a goal	“It has become more specified”, “I’m more interested in…”, “I now aim to…”
5	Changed goal features/journey	“Added a brand new goal”, “More aware of how long it will take”
N/A	Respondent did not answer the question	“N/A”, “I am still clueless”

Q9.5 Do you think that your attitudes towards statistics have influenced your career goals? If so, in what ways?

Q9.6 Do you think that your career goals have influenced your attitudes towards statistics? If so, in what ways?

Notation	Code	Examples
0	Non-statistics inclusive goals	“Never planned on using it in a job”, “I wouldn’t be confident in research”, “I would rather not”
1	Statistics inclusive goals	“Look into data analysis as a potential career”, “I am willing to learn for my future career”, “more interested in research”
2	Financial incentives	“Careers in statistics can be high paying”
3	Competition	“Not as many universities use it” (R)
4	Uncertainty	“Cautious that it will be a large part of my future career”

Expectancy-value variables

Responses to all qualitative questions were coded for the presence of expectancy-value variables in a top-down manner, where the codebook was developed to align with the quantitative scale used in our study.
