Quiz Statistics Key Terms

Standard deviation (SD): How much variation there was in the scores for this question or a measure of the spread of scores about the mean and hence the extent to which the question might discriminate. If F is very high or very low it is impossible for the spread to be large. Note however that a good SD does not automatically ensure good discrimination.

Discrimination index: This is the correlation between the weighted scores on the question and those on the rest of the test. It indicates how effective the question is at sorting out able students from those who are less able (students who score highly on this question are the same students who score highly on the whole quiz).

Point Biserial: Point Biserial calculates any possible correlation between the question score and the total quiz score. It measures the strength of the correlation between the two values, and shows either a positive or a negative relationship ranging from -1.00-+1.00.
