# The maths behind peer evaluation

Peer evaluation is used to calculate your peer-factor. Your shar= e of the group grades is the product of your peer-factor and the grades the= team has earned for its group assignments. The following example will illu= strate how the mathematics play out.

Imagine a team consists of four people: James, Mike, Susan, and Kiri. Du= ring the peer evaluation, each team member awards 100 points amongst the ot= her members based on their contribution to the team. Remember, that people = may not allocate points to themselves.

From the table above, one might infer that Kiri is regarded as a high co= ntributor to the team, whereas Mike is the lowest contributor.

The peer-factors are used in the following manner to determine each indi= viduals final grade for group work. For each 0.05 above or below 1.00, the = individual's share of the group grade is moved up or down. If this example = team actually got a B+ grade for their group work (e.g., For the performanc= e of their firm), they get the following grades as their share of the group= grade assignments:

In this way, each team members' share of group grades are distributed be= tween the themselves.
