A bonus exercise:

Check your random number generator using the KS test:

The following plot shows the cumulative frequency distribution for 1000 random numbers generated with mean = 0 and dispersion = 1. The x-axis is therefore in units of standard deviations.



2. Use the KS Test Calculator for this (plot generation is at the bottom of the results page)

• Paste in as Data set 1 the 1000 random numbers
• Paste in as Data set 2 this data set
• Calculate to recover the graph shown above
• Now try to generate random numbers with mean 0 and dispersion of 1 using any random number generator that you want and paste that data set in to data set 2 to comnpare against the model (data set 1)
