AVG macro

The AVG macro is available in IBM® Campaign and IBM® Interact.

AVG(data [, keyword])

The numerical values for which to compute the arithmetic mean. These values can be a constant value, a column, a cell range, or an expression evaluating to any of the above. For the format definition of data, see the "Macro Function Parameters" section in the chapter in this guide for your IBM® product.

This optional keyword determines how the computation is performed over the input data range. Select one of the following keywords:

ALL - Performs the computation on all cells in data (default)

COL - Performs the computation separately for each column of data

ROW - Performs the computation separately for each row of data

For more details on using keywords in IBM® Campaign, see Format Specifications.

Many macro functions take the keyword parameters {ALL | COL | ROW}. These keywords do not apply in IBM® Campaign because the input data is always a single column or field. The macro always behaves as if the COL keyword were specified. Therefore, you do not need to specify these keywords when you use IBM® Campaign.

AVG calculates the arithmetic mean or average of the cells in the specified data range. The arithmetic mean is calculated by summing the contents of all cells, then dividing the result by the number of cells. The number of columns that are returned by AVG depends on keyword.

If keyword is ALL, AVG returns one new column, containing a single value (the average of all cells in data).

If keyword is COL, AVG returns a new column for each input column. Each new column contains one value (the average of all cells in the corresponding input column).

If keyword is ROW, AVG returns one new column that contains the average across each row of data.

Blank cells are ignored in the calculation.

AVG is the same as the MEAN macro function.

Creates a column named TEMP containing a single value that is the arithmetic mean of the contents of column V1.

TEMP = AVG(V1:V3)

Creates a column named TEMP containing a single value that is the arithmetic mean of the contents of columns V1, V2, and V3.

TEMP = AVG(V1[10:20])

Creates a column named TEMP containing a single value that is the arithmetic mean of the cells in rows 10-20 of column V1.

TEMP = AVG(V1[1:5]:V4)

Creates a column named TEMP containing a single value that is the arithmetic mean of the cells in rows 1-5 of columns V1 through V4.

TEMP = AVG(V1:V3, COL)

Creates three new columns named TEMP, VX, and VY. The single value in the TEMP column is the arithmetic mean of the contents of column V1. The single value in the VX column is the arithmetic mean of the contents of column V2. The single value in the VY column is the arithmetic mean of the contents of column V3.

TEMP = AVG(V1[1:5]:V3, COL)

Creates three new columns named TEMP, VX, and VY, each containing a single value. The value in column TEMP is the arithmetic mean of the cells in rows 1-5 of column V1. The value in column VX is the arithmetic mean of the cells in rows 1-5 of column V2. The value in column VY is the arithmetic mean of the cells in rows 1-5 of column V3.

TEMP = AVG(V1, ROW)

Creates a column named TEMP, containing the same values as column V1 (the arithmetic mean of any number is itself).

TEMP = AVG(V1:V3, ROW)

Creates a column named TEMP where each cell entry is the arithmetic mean of the corresponding row across columns V1, V2, and V3.

TEMP = AVG(V1[1:5]:V3, ROW)

Creates a column named TEMP, where the cells in rows 1-5 contain the arithmetic mean of the corresponding row across columns V1 through V3. The other cells in TEMP are empty.
