Input

Set the drop-down list to Raw or Indexed.

Indexed

In this mode, one column contains levels of the factor variable and the corresponding response data are in another column.

Factor

Specify the factor column. Note that the fact column will be set as categorical if Text column.

Data

Specify the response data column.

: If you want to display numeric instead of text values for factor in result plot, please set the column designation of factor column to be Group

Raw

In this mode, response data from each level of the factor variable are stored in a separate column

Factor

Name

Enter the factor name.

Number of Levels

Default = 2

Specify number of levels. And each level will have its own Leveli controls. Note that the system variable @AML can be used to control the max number of supported levels for ANOVA, which is 25 by default. You can change the maximum number of levels by assigning new values to the @AML variable.

Leveli name

Default = Factori Leveli

Specify the level name. Auto uses the sheet Long Name.

Data

Leveli

Specify the data column for each level. Use the data selection controls beside each level

Descriptive Statistics

Check to include descriptive statistics results in the output report.

Significance Level

Set the significance level for one-way ANOVA.

Means Comparison

Choose methods of post-hoc pairwise comparisons:

Bonferroni
Significance Level	Specify the significance level for pairwise means comparison.
Tukey	Different methods for pairwise means comparison. (For more information see Algorithms).
Dunn-Sidak
Fisher LSD
Scheffe
Holm-Bonferroni
Holm-Sidak
Grouping Letters Table	Showed difference of mean value with letters. Same letter means no significant difference, while different letter mean significant difference between two groups.

Tests for Equal Variance

Choose test methods for homogeneity of variance.

Significance Level

Specify the significance level for equal variance tests.

Levene | |

Different methods for equal variance test.

(For more information see Algorithms).

Levene ()^2

Brown-Forsythe

Power Analysis

Choose to perform power analysis:

Actual Power	Specify whether to perform actual power test.
Hypothetical Power	Specify whether to perform hypothetical power test.
Significance Level	Specify the significance level for hypothetical power test.
Hypothetical Sample Size(s)	Specify the hypothetical sample size, using space to separate each entry.

Output

Graph Arrangement	Arrange Graphs into Columns Specifies number of columns to arrange output graphs. Arrange Plots of Same Type in One Graph Enable adding all data plots of the same type in one graph window.
Report Tables	Specifies the destination of report worksheet tables. Book Specifies the destination workbook. Accompanying BookName field registers output book name. <none>: Do not output report worksheet tables (BookName box is blank and read-only). <auto>: The location of the initial input data selection (Note that input data ranges can be from different workbooks). If input data is not in an Origin workbook, Origin will automatically pick an Origin workbook that fits (usually create a new workbook). <source>: The source data workbook. <new>: A new workbook. <existing>: A specified existing workbook. Sheet The destination worksheet (always <new> and named as SheetName). Result Log Enable to output the report to Result Log. Script Window Enable to output the report to Script Window. Notes Window Use this drop-down list to specify the destination Notes Window: <none>: Do not output to any Notes window. <new>: Output to a new Notes window. You can enter the desired name of the Note window here.
Plot Data	Specifies the destination to output the data for plots (you must select a Plots option, below). Book Specifies the workbook to output the plot data. <auto>: Follows Report Tables book settings unless you've set Book = <none>. <source>: The source data workbook. <report>: The report workbook. <new>: A new workbook. <existing>: A specified existing workbook. Sheet The destination worksheet (always <new> and named as SheetName).
Optional Report Tables	Specifies whether to include additional tables in report worksheet. Notes Notes table. Input Data Table for input data. Masked Data Table for masked data. Missing Data Table for missing data.

Plots

Box Chart
Bar Chart	Specifies whether to generate the plot in the report sheet. Note: If the Factor column is Set as Categorical, then the output graph will be plotted according to the categorical order customized through (Column Properties) Categories tab from Factor column.
Means Plot (SD as Error)
Means Plot (SE as Error)
Means Comparison Plot	This is only available when post-hoc pairwise comparisons will be performed.(controlled in Means Comparison tree node). Specifies whether to output means comparison plot(s) for all selected method(s).
