Question
Transcribed Image Text:1. A research team is interested in investigating how sleep
deprivation and memory training influence memory recall
(operationalized/measured by the number of words participants
can remember after studying a list of words). Some participants
are not permitted to sleep during the night before the study,
some participants are allowed only four hours of sleep, and
some participants are allowed eight hours of sleep. With
reference to memory training, some participants get memory
training prior to studying the word list, and some do not get
memory training prior to studying the word list. Participants are
randomly assigned to one of six unique groups. The research
team is measuring number of words correctly recalled. Factor A
is Memory Training and Factor B is Sleep Deprivation.
Transcribed Image Text:d.) Imagine a few months later, the research team decided to try

(i.) a main effect for Factor A, (ii) a main effect for Factor B,
and/or (iii.) an AxB interaction effect. Explain how you arrived

of Factor A, a main effect of Factor B, and an AxB interaction.
Assume any difference between means is significant. As a
