Project Settings include global statistical significance settings that define whether significance is displayed, how significant differences are indicated, which comparison method is used, and the significance thresholds applied throughout the project.
Go to the Project Settings → Settings → Significance. Here you will find the main settings:
1. If you don't have the 'Significance' button on the screen
-
go to the Meta-Editor → Settings → Significance;
-
check that the 'Hide on DVI' box is not ticked.
2. To use a weighted base for significance calculation
-
go to the Meta-Editor → Settings → Significance;
-
tick the 'Use weighted base when calculating significance' box.
3. To exclude values with a low base from significance calculations
-
go to the Meta-Editor → Settings → Significance;
-
tick the 'Don't calculate Significance for values with Low Base' box.
4. To enable the advanced significance test
-
go to the Meta-Editor → Settings → Significance;
-
tick the 'Advanced Sig Test with Audience Overlap Detection' box.
5. To select significance thresholds
-
go to the Meta-Editor → Settings → Significance;
-
tick boxes to enable up to 3 comparison levels. You can use all 3 thresholds concurrently.
-
Confidence Level 90% (p<0.10);
-
Confidence Level 95% (p<0.05);
-
Confidence Level 99% (p<0.01).
-
6. You can select the indication that will be applied by default
-
Arrows - different sizes of arrows depending on the threshold next to the text in the cell;
-
Dots - different sizes of dots depending on the threshold next to the text in the cell;
-
Font color - the text in the cell has a color;
-
Fill color - the entire cell is filled with color;
-
Chart color - coloring of chart segments.
Note that the indicator and color settings here only apply to the defaults; if you change them on the crosstab, those changes will take precedence.
7. Legend
In the significance settings, you can adjust labels to display significance on a crosstab/chart. By default, these labels are used: ‘Value is higher than ${COMPARAND}’ or ‘Value is lower than ${COMPARAND}’. You can edit the labels on the appropriate lines.
8. Default colors of indication
The two color pickers allow you to define custom colors for significance indicators. These colors are applied as the default across the entire project unless they are overridden in the Comparison settings of an individual crosstab or dashboard.
