Oneway anova reports
Activates Box Plots from the Display Options menu.
The Means/Anova/Pooled t option appears only if the X factor has two levels.
Produces a t-test report assuming that the variances are not equal. See The t-test Report.
Performs four tests for equality of group variances. Also gives the Welch test, which is an anova test for comparing means when the variances within groups are not equal. See Unequal Variances.
Set α Level
You can select an option from the most common alpha levels or specify any level with the Other selection. Changing the alpha level results in the following actions:
Plot Actual by Quantile generates a quantile plot with the response variable on the y-axis and quantiles on the x-axis. The plot shows quantiles computed within each level of the categorical X factor.
Plot Quantile by Actual reverses the x- and y-axes.
Line of Fit draws straight diagonal reference lines on the plot for each level of the X variable. This option is available only once you have created a plot (Actual by Quantile or Quantile by Actual).
Save Residuals saves values computed as the response variable minus the mean of the response variable within each level of the factor variable.
Save Standardized saves standardized values of the response variable computed within each level of the factor variable. This is the centered response divided by the standard deviation within each level.
Save Normal Quantiles saves normal quantile values computed within each level of the categorical factor variable.
Save Predicted saves the predicted mean of the response variable for each level of the factor variable.
Draws a horizontal line through the mean of each group proportional to its x-axis. The top and bottom points of the mean diamond show the upper and lower 95% confidence points for each group. See Mean Diamonds and X-Axis Proportional.
Draws the overall mean of the Y variable on the plot.
Makes the spacing on the x-axis proportional to the sample size of each level. See Mean Diamonds and X-Axis Proportional.
Adds small spaces between points that overlay on the same y value. The horizontal adjustment of points varies from 0.375 to 0.625 with a 4*(Uniform-0.5)5 distribution.
(Only appears when the Matching Column option is selected.) Connects matching points.
Only appears when the Matching Column option is selected.) Draws dotted lines to connect cell means from missing cells in the table. The values used as the endpoints of the lines are obtained using a two-way anova model.
