Normal Density Curve Properties. The tails on either end of the curve are asymptotic 7. Introduction to Relative Frequency Histograms. This means the center of the curve is the mean. O The mean median and mode equal the same value.
95 of the area under the curve is within one standard deviation of the mean. In a normal distribution the mean mean and mode are equalie Mean Median Mode. The density curve always lies on or above the horizontal axis. For example it has the property of symmetricity. All density curves including normal density curves have two basic properties. For a normal density function to be a curve it must meet the following requirements of the probability distribution.
The total area under the curve equals 1.
Properties of the Normal Density Curve 1. The mean and the median equal each other. Properties of the Normal Density Curve Properties of the Normal Density Curve. The total area under the curve equals 1. Explain the role of area in the normal density function Probability Density Functions In Chapter 6 we focused on discrete random variables random variables which take on either a finite or countable number of values. The curve will never dip below the x-axis.
