Our students need to know the following information when they look at their grades - the percentage mark, the class average, the mean of the class and the z-score (standard score).
The z-score is
where:
- x is a raw score to be standardized;
- μ is the mean of the population;
- σ is the standard deviation of the population.
The quantity z represents the distance between the raw score and the population mean in units of the standard deviation. z is negative when the raw score is below the mean, positive when above.
Is there anyway that we can have this information displayed for each student when they view their grades?
Thanks in advance.
