An educator was interested in "positive feedback" versus "negative feedback" while in
the classroom as they conduct an activity as they might influence the number of
questions 4th grade students will ask. Specifically, the educator speculates that there
will be a difference between the two conditions that will foster how comfortable
students feel asking questions, but the educator is not sure which way the difference
will go. On a random basis, the educator divided a class of eighteen 4th graders into
two different styles of "feedback" during activities in class: a positive feedback group
of nine children; and a negative feedback group of nine children in which students
received negative feedback while conducting an activity in the class. The data are
presented below and represent the number of questions asked by students while
learning the material in class.
