  • The bimodality in responses proved to be the result of two differentiating variables: access to a household car as an alternative to using public transportation (buses) and the frequency of using buses (between high users, who used buses two or more times per week, and low users, who used them infrequently, or less than once a week).

Morphology

bimodality = modality (transparent) = bi + modal + ity

A regular prefixation of 'modality' with 'bi-' to indicate 'two' modalities (i.e., two modes); formation is straightforward though the base term is somewhat technical.

Etymology

The word bimodality comes from bi- meaning 'two' and mode meaning 'way' or 'form'. So, bimodality means having two different types or two peaks in data, like two hills on a graph that show two groups.
