MEAN macro

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

The numerical values to compute the arithmetic mean of. This 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.

keyword

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

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

See DATE macro for more details on using keywords.

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 will always behave as if the COL keyword were specified. Therefore, you do not need to specify these keywords when using IBM® Campaign .

Description

MEAN 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 divided by the number of cells. The number of columns returned by MEAN depends on keyword.

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

If keyword is COL, MEAN 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, MEAN returns one new column containing the average across each row of data.

Blank cells are ignored in the mean.

MEAN is the same as the AVG macro function.

Examples

TEMP = MEAN(V1)

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

TEMP = MEAN(V1:V3)

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

TEMP = MEAN(V1[10:20])

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

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

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

TEMP = MEAN(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, and the single value in the VY column is the arithmetic mean of the contents of column V3.

TEMP = MEAN(V1[10:20]: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 10-20 of column V1, the value in column VX is the arithmetic mean of the cells in rows 10-20 of column V2, and the value in column VY is the arithmetic mean of the cells in rows 10-20 of column V3.

TEMP = MEAN(V1:V3, ROW)

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

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

Creates a new 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.
