One-Way ANOVA Options
- Statistics
- Choose one or more of the following:
- Descriptive
- Calculates the number of cases, mean, standard deviation, standard error of the mean, minimum, maximum, and 95% confidence intervals for each dependent variable for each group.
- Fixed and random effects
- Displays the standard deviation, standard error, and 95% confidence interval for the fixed-effects model, and the standard error, 95% confidence interval, and estimate of between-components variance for the random-effects model.
- Homogeneity of variance test
- Calculates the Levene statistic to test for the equality of group variances. This test is not dependent on the assumption of normality.
- Brown-Forsythe
- Calculates the Brown-Forsythe statistic to test for the equality of group means. This statistic is preferable to the F statistic when the assumption of equal variances does not hold.
- Welch
- Calculates the Welch statistic to test for the equality of group means. This statistic is preferable to the F statistic when the assumption of equal variances does not hold.
- Missing Values
- Controls the treatment of missing values.
- Exclude cases analysis by analysis
- A case with a missing value for either the dependent or the factor variable for a given analysis is not used in that analysis. Also, a case outside the range specified for the factor variable is not used.
- Exclude cases listwise
- Cases with missing values for the factor variable or for any dependent variable included on the dependent list in the main dialog box are excluded from all analyses. If you have not specified multiple dependent variables, this has no effect.
- Confidence Interval
- By default, a 95% confidence interval for the difference between the mean and the hypothesized test value is displayed. Enter a value between 1 and 99 to request a different confidence level.
- Means plot
- Displays a chart that plots the subgroup means (the means for each group defined by values of the factor variable).
