Freeman Introduction to the Practice of Statistics ISBN:9781319013387 Author:David S. Moore, George P. McCabe, Bruce A. Craig Publisher:W. H. Freeman Which graph is the shape of a normal curve?A normal distribution is a true symmetric distribution of observed values. When a histogram is constructed on values that are normally distributed, the shape of columns form a symmetrical bell shape. This is why this distribution is also known as a 'normal curve' or 'bell curve'.
How do you determine if a graph can represent a normal density function?A graph could represent a normal density function if it is symmetric about its mean, it has a single peak at the mean, the highest point occurs at the mean, and if it approaches, but does not reach, the horizontal axis as x increases without bound and decreases without bound.
What defines a normal curve?normal curve. noun. statistics a symmetrical bell-shaped curve representing the probability density function of a normal distribution. The area of a vertical section of the curve represents the probability that the random variable lies between the values which delimit the section.
