Syntax
ANOVA1(inprng, outrng, grouped, labels, alpha)
ANOVA1?(inprng, outrng, grouped, labels, alpha)
Inprng is the input range.
Outrng is the first cell (the upper-left cell) in the output table or the name, as text, of a new sheet to contain the output table. If FALSE, blank, or omitted, places the output table in a new workbook.
Grouped is a text character that indicates whether the data in the input range is organized by row or column.
If grouped is "C" or omitted, then the data is organized by column.
If grouped is "R", then the data is organized by row.
Labels is a logical value that describes where the labels are located in the input range, as shown in the following table:
| Labels | Grouped | Labels are in |
| TRUE | "C" | First row of the input range. |
| TRUE | "R" | First column of the input range. |
| FALSE or omitted | (ignored) | No labels. All cells in the input range are data. |
Alpha is the significance level at which to evaluate critical values for the F statistic. If omitted, alpha is 0.05.
