Data is facts and statistics collected together for reference or analysis. When presented as a list, data can be difficult to understand. We looked at two different ways to organize and display data so that it is easier to read, interpret, and understand.
The first display is a line plot. Line plots are number lines with "X" or circles above numerical values to show the frequency of data values. The second display type is a box-and-whisker plot. This is also known as a five-point summary because it is uses the least value, first quartile, median, third quartiles, and greatest value.
