Assuming that your data has a Gaussian distribution then the Gaussian (normal) curve is defined by the mean and the standard deviation, both of which can be found using the Standard Deviation and Variance function under the Probability and Statistics portion of the Mathematics menu.
Based on your question I suspect that your data is not Gaussian in nature and you are wanting to make it into a Gaussian form, as in a professor grading on the curve. For this you could define a mean and standard deviation, sort the data points from smallest to largest, and then step through the array assigning values for each data point which fits the probability curve (i.e., if there are 100 data points then the 1st data point would correspond to the point below which 1% of the
data lies). With this method you need to make sure that you monitor cases where more than one sample have the same value. There may be other ways to do this about which I am not aware.
Hope that helps.
