Document Summary
Total area under curve = 1: 68. 3% (+/-) 1 standard deviation, 95. 4% (+/-) 2 standard deviations, 99. 7% (+/-) 3 standard deviations. Probability density function: a function used to compute probabilities for a continuous random variable. The area under the graph of a probability density function over an interval represents probability. Uniform probability distribution: a continuous probability distribution for which the probability that the random variable will assume a value in any interval is the same for each interval of equal length. Its probability density function is bell-shaped and determined by its mean and standard deviation . Standard normal probability distribution: a normal distribution with a mean of zero and a standard deviation of one. Continuity correction factor: a value of . 5 that is added to or subtracted from a value of x when the continuous normal distribution is used to approximate the discrete binomial distribution.
