Chapter 6 The Normal Distribution And Other Continuous A continuous probability distribution, bell shaped and symmetric in appearance with a theoretically infinite range and defined by its two parameters, μ and σ, the population mean and population standard deviation, that represents (at least approximately) a wide variety of numerical random variables in the physical sciences, social sciences. To translate from x to the standardized normal “z” distribution, subtract the mean, μ, and divide by the standard deviation, σ. that is, = ( % ) ≈ %. the standard normal z distribution always has mean = μ = 0 and standard deviation = σ = 1. values above the mean have positive z values. values below the mean have negative z values.
Chapter 6 The Normal Distribution And Other Continuous 6.1: the normal distribution. the normal, a continuous distribution, is the most important of all the distributions. it is widely used and even more widely abused. its graph is bell shaped. in this chapter, you will study the normal distribution, the standard normal distribution, and applications associated with them.
