17.1 Notes Defenitions: 1. Standard Deviation: Important measure of spread; used to determine normal ( or approximately normal) distribution; symbolized with the greek letter sigma (σ) 2. Point of Infection: Curvature gradually changing from one side to another 3. The 689599.7 Rule: Used for normal distribution a. 68% of the observations are within one standard deviation of the mean b. 95% of the observations are within two standard deviations of the mean c. 99.7% of the observations are within three standard deviations of the mean Colors Red: Mean Blue: 1 Standard Deviations; 68% Purple: 2 standard deviations; 9
