Summary
In this chapter, we have demonstrated various techniques for visualizing data, including the familiar scatter plots, line graphs, bar charts, and histograms. These were illustrated using the tools provided in Microsoft Excel. We also saw examples of time series data and computed their moving averages both in Excel and in Java.
We saw how visualizing (graphing) various binomial distributions can clarify how they lead to the normal distribution. We also saw, with a simple Java program, how the exponential distribution can be used to predict arrival times of random events.
