Image caption, The advantage of using a frequency polygon is that it allows similar sets of data to be plotted on the same graph. Comparisons between the two sets can then be made. For example ...

The resulting data and graph are shown below. The frequency is derived from the data using this formula: frequency = 300,000,000 m/s / (2 * half-wavelength measurement) The half-wavelength ...

The type of graph you use depends on the type of data you want to represent. In a bar chart, the height of the bar shows the frequency of the result. As the height of bar represents frequency ...
