A frequency distribution curve is a graphical representation of the distribution of data. It is a line graph that shows the frequency of each value in a data set. The frequency of a value is the number of times that value appears in the data set.
A frequency distribution curve can be unimodal, bimodal, or multimodal. A unimodal curve has a single peak, or lump. A bimodal curve has two peaks, and a multimodal curve has three or more peaks.
A frequency distribution curve can also be symmetrical or asymmetrical. A symmetrical curve is one that is the same on both sides of its center line. An asymmetrical curve is one that is not the same on both sides of its center line.
