After you create an analysis, the modify menu will become available. The options in the modify menu allow you to interact with the settings in your analysis. In this menu, you can also find statistical test options available in Infotools Harmoni.
 As with other menus, the options in this menu are contextual.
 Actions will apply to the entire table by default unless you select a particular column, row or cell.
 Icons will turn orange when the selected analysis options are applied.
 Icons that display an arrow at the bottom allow expanding. This will open the menu and give you further analysis options.
 During your session, your setting preferences are retained across projects and analyses unless:
 You end your session (log out or close browser).

2. Format  Values displayed in an analysis
Any row or column in an analysis can display different values including counts (weighted or unweighted), percentages, averages, etc.
a) Add/Replace Switch
The add/replace switch allows creating tables that show either complimentary data displays or singular displays. This can be applied to a selected part of the table/chart or the whole table/chart.
Replace
While the add/replace switch is on replace any data calculation change will replace the currently selected item (or the entire table if nothing is selected).
Add
If the switch is moved to add:
 Any new data type/calculation selected will be added as a new column or row next to the item you have selected.
 If nothing is selected, the default will be to create a new column of the data display for each of the original columns of that table.
b) Analysis setting options

Infotools Harmoni applies bankers rounding.
Bankers Rounding is an algorithm for rounding quantities to integers, in which numbers which are equidistant from the two nearest integers are rounded to the nearest even integer.
We round 0.5 to the nearest even digit.
Example:
 7.5 rounds up to 8 (because 8 is an even number)
 but 6.5 rounds down to 6 (because 6 is an even number)
3. Selected column or row settings
You can select any row or column in the analysis and display different value types, including counts (weighted or unweighted), percentages, averages, etc.
a) Hide
In addition, you can select columns and/or rows and hide these items from the view.
 The items will still remain part of the overall calculation of the analysis, but hidden from the view.
 If you want these items to be excluded from the overall calculation of the analysis, you can use the View Total Option.
b) Rank
Icon  Name  Description 
HIDE  Hide 
It only appears when something is selected. Hides the selected items. Hidden items can be added back into the analysis by using the select menu. 
Rank 
It only appears when a header column or row is selected. Rank from high to low, low to high and off/default. Column selection will rank items within that column (vertical). Selecting a row will rank items within that row (horizontal). 
4. Suppress items from analysis
Icon  Name  Description 
ZERO  Suppress zero 
Suppresses items where the numerator is zero. It only appears when nothing is selected in your analysis. 
NULL  Suppress null 
Suppresses items where both the numerator and denominator are zero. It only appears when nothing is selected in your analysis. 
5. Tests  Statistical Testing
a) Reference for testing
It only appears when a single row or column is selected. The selected row or column becomes the reference for significant difference calculations.
Previous Period Referencing
When a timebased axis is a part of your analysis (generally columns/across) you have the ability to set significance testing to be based on a rolling period. This could be the previous period or even the previous 4th period. Depending on your time axis this allows you to set a reference to a preferred time period.
b) Significant Differences
Statistical significance of the differences between the results for one group and a reference group (often the total sample).
An analysis can contain discrete or continuous variables.
 Discrete variables contain labeled responses that have a yes, no or missing response for each record. The statistical significance of the difference between two discrete variables is calculated using both counts, and bases. The statistical test used is the chisquared test.
 Continuous variables are called 'measures' or 'values'. Measures in an analysis may either be sums (i.e. totals) or averages. For comparisons of continuous variables (measures or averages), the statistical test used to determine significant differences is a ttest. The test is applied using numerical values.
The significance level is the likelihood that the difference is not due purely to chance. If the confidence level is set to 95%, the change is said to be statistically significant, as there’s only a 5% chance that the difference is due purely to chance.
Infotools Harmoni applies an automatic (and generally industry default) confidence level of 95% for significant difference calculation. As a user, you can override this via the modify menu. Site settings can be controlled via a site key.
Significance testing is represented using red and green arrows.
c) Low sample size
When the percentages shown in tables are based on small subsamples, the results may be unreliable. The Low Sample Size feature hides or fades values in the table when the unweighted value of the denominator used for percentage calculations is lower than a specified level.
 Low Sample warnings:
 Low sample  Transparency is applied to the results to match the warning threshold.
 Too low sample  An asterisk (*) is shown instead of the result.
d) Effective Base
Traditionally the test for significance uses the unweighted base in the calculation. This can lead to an overestimate of the significant difference between the two data cells when extreme weighting has been applied. By using the effective base instead of the unweighted base in the calculation we can adjust for this overestimate.
The effective base can be set through personalization keys.

6. Analysis Layout
a) Flip analysis
Flips the analysis so what was across moves into the down dimension, and vice versa. This has the same functionality as clicking on the by between the across and down dimensions in the analysis title.
b) Reorder columns and rows
Allows shifting selected columns and/or rows in an analysis table view. For this option to become available, you must first select the column(s) or row(s) you want to move.
Once you have moved:
 The order is retained when saving a view.
 The order applies to Excel and PowerPoint exports.
 Selectors will also reflect the order of the items. The selector won’t reflect the change if the order change is different across nested items.
Reorder is not available when ranking has been used. If you want to change the order of items you first need to remove the ranking.
Icon  Name  Description

8. Data Labels
a) Discover
Discover is a tool to profile a target group against a set of descriptor variables. It will show you which of these descriptors best describe your group and compare these with other groups.
On a table view, select the group you are interested in profiling. Selecting will enable the Discover option located in the modify menu under data labels.
b) Heat map
Heat map is another statistical test option available in Infotools Harmoni. Using a stepped coloring from green to red, you can quickly see the highs and lows of significance in the results as a visual distribution across the entire table.
The heat map colors the cells in the table to show the quintile distribution within a row. It compares the data within each row and divides into 5 quintiles (colors).
A quintile is a statistical value of a data set that represents 20% of a given population, so the first quintile represents the lowest fifth of the data (1% to 20%); the second quintile represents the second fifth (21% to 40%) and so on.
c) Chart labels
You can interact with the data labels you want to display in your chart. Options include:
 Show/hide labels.
 Show only labels for items where there is a significant difference to the reference.
 Show the value gap of items when compared to the reference.
 Optimize the label placement to avoid overlaps that would make labels hard to read.
d) Show Sample Size on Charts
When creating an analysis and choosing to visualise you can display the sample size within the graph.
The show sample size option can be switched on or off through the modify menu. The setting selected is sticky for all the analyses in your session.
If your percentages are based on the down dimension, which is the default behavior, the sample size appears in the across legend labels. If you have changed the percentages to be based on the across dimension, the sample size will appear in the graph legend. The sample size is the unweighted base.
The sample size is the unweighted base (n=uB).
Sample size on export to PowerPoint and Excel
When show sample size option is on:
 In Excel  the sample size is available even when you can't see in the Infotools Harmoni table.
 In PowerPoint  the sample size is part of the labels on export to PowerPoint.
Show sample size option is not available:
