Group 1 individuals learned the software using a visual manual (multimodal instruction), while Group 2 individuals learned the software using a textual manual (unimodal instruction). The following data represent scores that the students received on an exam...

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers.

She then asked them to rate how likely they were to cheat on an course-testings if the opportunity presented itself with very limited chance for consequences. The students rated their desire to cheat on a scale ranging...
