Line Plot is a diagrammatic representation of data displayed on a number line. For any

Statistical Graph, the data has to be tallied and organized in some form. A

frequency table is used to tally or count the number of different categories and find their frequencies. Line Plot provides a method to tally and organize data direct on the chart when the categories being tallied are numbers. For this matter, Line Plots can also be understood as data tallied on a number line.

A line Plot uses X marks above a number line to show the frequencies. The X marks can also be replaced with a dot or some picture, motif or design related to the data set.

**The Line Plot is also sometimes called a Dot Plot.**Line Plots are not only a useful data display, but can also be used for data analysis. Each data value is clearly represented on a Line Plot. A quick observation of a Line Plot gives the range and mode of the data set direct. As the data values are placed in numerical order, the median can be easily found using a Line Plot. Line Plots clearly show clusters, gaps and outliers in data sets.
