Density Curves - STATS4STEM
A density curve is a graphical representation of a numerical distribution where the outcomes are continuous. In other words, a density curve is the graph of a continuous distribution.
Density Curve Examples - Statistics How To
A density curve is a graph that shows probability. The area under the curve is equal to 100 percent of all probabilities. As we usually use decimals in probabilities you can also say that the area is equal to 1 (because 100% as a …
