Multivariate+AS+1.10


 * 10 April**

Starter:
A train company keeps records of the number of trains that were late for two different months and these data are shown below January 1 0 2 7 3 1 2 4 5 1 2 4 7 4 3 0 1 4 1 3 2 1 2 3 4 5 6 0 1 2 9

February 5 6 5 4 3 7 8 1 4 3 4 5 6 4 3 2 6 4 8 8 5 3 4 3 5 4 4

Find the mean median and mode values for each month.

When completed you must take 'notes' about the distribution on data and key words you can use to describe it, eg: symmetrical distribution, clusters etc.
