l Standard Deviation
standard deviation (σ) = (((x - μ)²) / n)
l x = a Participant’s score
l μ = mean total score
l n = total number of Participants
The discrimination index can then be computed with the following formula:
discrimination index = ((Mp-Mq) / σ) * ((Np*Nq)/((Np+Nq) * (Np+Nq-1))
l Mp = mean total score of the group of Participants that answered the question correctly
l Mq = mean total score of the group of Participants that answered the question incorrectly
l Np = total number of Participants that answered the question correctly
l Nq = total number of Participants that answered the question incorrectly
l σ = standard deviation of scores for the entire set
