Researchers wanted to know whether there was a difference in
comprehension among students learning a computer program based on
the style of the text. They randomly divided 36 students of similar
educational level, age, and so on, into two groups of 18 each.
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 divided her 60
students into three groups (low, middle, and high) based on their
mean course-testings score on the previous three tests. 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...

Edward wanted to know whether students’ attitudes towards the
extra-curricular activities sponsored by EKU differed as a function
of class year and gender. So Edward randomly surveyed 12 freshman,
12 sophomores, 12 juniors, and 12 seniors, with each class year
sample having equal numbers of male and female participants. Each
student was asked to rate their attitude of EKU’s extra-curricular
activities on a 1 – 10 scale with 1 being totally negative and 10
being totally positive.
