The Graphical Summary… tool is a quick way of producing an overview of a column of data. The following example shows us the output comprising a histogram, the Anderson-Darling test for normality, mean, standard deviation, and more.
Here, we will use the data from the Oxford weather station and produce a summary of the amount of rainfall in mm for each month, for all the results from 1853 onwards.
We will use the data from the Oxford weather station in this example. This data is from the Met Office website and can be found at http://www.metoffice.gov.uk/climate/uk/stationdata/. Select the Oxford station.
The data is made available in the Oxford Weather.txt
file; this preserves the format from the website. This data is also available in the Minitab Oxford weather (cleaned).mtw
file, and using this worksheet correctly imports itself into Minitab for us.
