Continuous Probability Distribution - answer - The probability distribution of a continuous random variable Standard Normal Distribution - answer - A normal distribution with a mean of 0 and a standard deviation of 1. Z Score - answer - The number of standard deviations a particular score is from the mean. 1. Z = 0 (The value is equal to the mean) 2. Z = - (The value is below the mean) 3. Z = + (The value is above the mean) Z = Value - Mean / Standard Deviation Properties of the Standard Normal Distribution - answer - 1. The cumulative area is close to 0 for z-scores close to z = -3.49 2. The cumulative area increases as the z-scores increase. 3. The cumulative area for z = 0 is 0.5000. 4. The cumulative area is close to 1 for z-scores close to z = 3.49. Bell Shaped Distribution - answer - A probability distribution in which the highest frequency occurs in the middle and frequencies tail off to the left and right of the middle.
