Ap Statistics Lesson 10 The Normal Distribution Normal The normal equation. the normal distribution is defined by the following equation: the normal equation. the value of the random variable y is: y = { 1 [ σ * sqrt (2π) ] } * e (x μ)2 2σ2. where x is a normal random variable, μ is the mean, σ is the standard deviation, π is approximately 3.14159, and e is approximately 2.71828. This is a summary video for unit 1 of ap statistics. in this video the normal distribution is explained and examples shown!if you want more summary videos,. Normal distribution. the normal distribution is a continuous probability distribution that is symmetric and bell shaped. it is defined by its mean and standard deviation. many real world variables are approximately normally distributed. the standard normal distribution refers to a normal distribution with a mean of 0 and standard deviation of 1.

Figure 5.3 : the z distribution is a probability distribution (total area = 1) and symmetric, so the area on either side of the mean (which is 0) is a half. you will need to remember this information as you calculate areas using the standard normal distribution table. figure 5.4 : the units of z in p(z) are standard deviations. In the special distribution simulator, select the normal distribution. vary the parameters and note the shape and location of the probability density function. with your choice of parameter settings, run the simulation 1000 times and compare the empirical density function to the true probability density function.
