STAT1	The STAT1 function provides a range of one-variable statistics.
	It can calculate all or any of					x	, Σ, Σ², s, s², σ, σ², serr,
	∑(xi – x)2 , n, min, q1, med, q3, and max.
			STAT1(Input range, [mode], [outlier
			removal Factor], ["configuration"])
	Input range is the data source (such as A1:D8).
	Mode defines how to treat the input. The valid values are:
			1 = Single data. Each column is treated as an
			independent dataset.
			2 = Frequency data. Columns are used in pairs and the
			second column is treated as the frequency of appearance
			of the first column.
			3 = Weight data. Columns are used in pairs and the
			second column is treated as the weight of the first
			column.
			4 = One–Two data. Columns are used in pairs and the 2
			columns are multiplied to generate a data point.
	If more than one column is specified, they are each treated as
	a different input data set. If only one row is selected, it is
	treated as 1 data set. If two columns are selected, the mode
	defaults to frequency.
	Outlier Removal Factor: This allows for the removal of any
	datapoint that is more than n times the standard deviation
	(where n is the outlier removal factor). By default this factor is
	set to 2.
	Configuration: indicates which values you want to place in
	which row and if you want row or columns headers. Place the
	symbol for each value in the order that you want to see the
	values appear in the spreadsheet. The valid symbols are:
		H (Place column headers)						h (Place row headers)
				Σ	Σ²			s	s²	σ
		x
		σ²		serr	∑(xi – x)2			n	min	q1
		med		q3	max
