What criterion are you using to compare? If the distribution is relatively normal:
Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability between score and mean for the Z score. Multiply by 100 for percent increase.
