Factor analysis allowed grouping the multiple-choice survey questions into 19 drivers of people’s decisions to join the bus. Factor analysis searches for statistical correlation among the responses for the different survey questions.

We have facilitated two focus groups with exis-ting and potential bus users to develop the survey questions Q01 till Q40.

The focus groups have been trans-cribed and ana-lysed using quali-tative research methods.
