A density curve, also called a density function, is a graphical representation of the relative frequency distribution of a continuous random variable. The type of distribution most commonly represented by a density curve is the normal distribution, but any distribution of a continuous variable may be represented by a density curve.
Density curves are always drawn as a continuous curve above the horizontal axis, and have the property that the curve encloses an area of 1 above the axis.
