How do you test the oscillator circuit you just made that runs between 200MHz and 380MHz if all you have is a 100MHz oscilloscope, a few multimeters and a DC power supply? One answer is to put ...

Visual Representation of a Frequency Distribution Both histograms and bar charts provide a visual display using columns, where the y-axis represents the frequency count while the x-axis represents ...

Note how the total adds up to 100%. Bar charts and line graphs can be combined. Climate graphs are an example of this. The x-axis shows the months of the year and there are two y-axes to show ...

In some situations, a count (frequency) is available for each category, or you can compress a large data set by creating a frequency variable for the categories before applying the PARETO procedure.
