1166 ONEWAY<br />

• Up to 10 RANGE subcommands are allowed. The effect is cumulative. If you specify more<br />

than one alpha value for different range tests, the last specified value takes effect for all<br />

tests. The default is 0.05.<br />

• Keyword MODLSD on the RANGE subcommand is equivalent to keyword BONFERRONI<br />

on the POSTHOC subcommand. Keyword LSDMOD is an alias for MODLSD.<br />

PLOT MEANS Subcommand<br />

PLOT MEANS produces a chart that plots the subgroup means (the means for each group<br />

defined by values of the factor variable).<br />

STATISTICS Subcommand<br />

By default, ONEWAY displays the ANOVA table showing between- and within-groups sums<br />

of squares, mean squares, degrees of freedom, F ratio, and probability of F. Use STATISTICS<br />

to obtain additional statistics.<br />

BROWNFORSYTHE Brown-Forsythe statistic. The Brown-Forsythe statistic, degrees of<br />

freedom, and the significance level are computed for each dependent<br />

variable.<br />

WELCH Welch statistic. The Welch statistic, degrees of freedom, and the significance<br />

level are computed for each dependent variable.<br />

DESCRIPTIVES Group descriptive statistics. The statistics include the number of<br />

cases, mean, standard deviation, standard error, minimum, maximum,<br />

and 95% confidence interval for each dependent variable for each<br />

group.<br />

EFFECTS Fixed- and random-effects statistics. The statistics include the standard<br />

deviation, standard error, and 95% confidence interval for the<br />

fixed-effects model, and the standard error, 95% confidence interval,<br />

and estimate of between-components variance for the random-effects<br />

model.<br />

HOMOGENEITY Homogeneity of variance tests. The statistics include Levene statistic,<br />

degrees of freedom, and the significance level displayed in the Test of<br />

Homogeneity of Variances table.<br />

NONE No optional statistics. This is the default.<br />

ALL All statistics available for ONEWAY.<br />

MISSING Subcommand<br />

MISSING controls the treatment of missing values.<br />

• Keywords ANALYSIS and LISTWISE are alternatives. Each can be used with INCLUDE or<br />

EXCLUDE. The default is ANALYSIS and EXCLUDE.
