.SH NAME
oneway/ttest \- one way analysis of variance and t-test
.SH SYNOPSIS
.B oneway
[-t] [-s splitter] [group names]
.SH DESCRIPTION
.I oneway
does a one-way analysis of variance on data from different groups.
The group sizes can differ,
in which case,
a weighted means solution is used.
.PP
The input format is simple:
each group's data is separated from other groups' by including
a special value, called the splitter.
.SH OPTIONS
.PP
Group names can be supplied on the command line.
Otherwise, names like ``Group\ 1'' are used.
.TP
.B -s splitter
This value is used to tell when one group's data ends and another's begins.
.TP
.B -t
Request a between group's t-test format for the significance test.
This option is automatic when the program is called
.I ttest.
.SH EXAMPLE
.P
Suppose you had two groups of data in two files, called ``long'' and ``short.''
To compare these, you would do something like:
.ce
echo 999 | cat long - short | oneway -s 999 long short
.SH ALGORITHM
The algorithm follows Guilford & Fruchter's
.I "Fundamental Statistics for Psychology and Education (5th Edition)."

.SH BUGS
.I oneway
duplicates some functionality of
.I anova (1)
but is included to make this common type of data more easily analyzed.
.SH KEYWORDS
