Weekdays and Holidays Volcano Plot

The Weekdays and Holidays Volcano Plot section is shown below:

It contains the following elements:

•	One Data Filter .

Enables you to subset subjects based on country of origin and study site. Refer to Data Filter for more information.

•	One Volcano Plot .

The volcano plot is used to determine the deviation of the proportion of study visits at each study site that occur on specific weekdays and holidays with the overall proportions for the whole study. Those sites plotting close to 0 on both axes show little or no difference from the averages across all study sites. Those sites plotting more distally (such as site 42 in the figure above, for example) show deviation from the averages.
