Strongly Associated with: normal distribution, bell curve  
Notes:
A theoretical data distribution which appears bell shaped, is symmetrical about the mean and has the most probable scores concentrated around the mean. Progressively less likely scores occur further away from the mean. 68.26% of the scores lie within one standard deviation either side of the mean, 95.44% of the scores lie within 2 standard deviations either side of the mean and 99.75% fall within three standard deviations.
psy.standrews.ac.uk/resources/glossary.shtml The exact shape of the bell curve is determined by the standard deviation. The mean and median are at the same point. Also called: normal distribution or a bell curve.
