Column  Description  Example 

Table of contents  A list of the references within the book. References with 0 results are not shown.
The + button will display lower references, such as chapter and paragraph. 

Actual  The frequency of the search term within the reference.  The search term occurs 1,010 times in Comedies. 
≈Expected  If search hits were evenly distributed throughout the book, this is the number of hits we would expect to see in a given reference. (Based on the size of the reference and the total
number of search hits.) If you have filters on your search query, the expected frequency will be inaccurate. Likewise, subwords or tagwords in your search argument will distort the statistic. There is a size variable used in the computation, and it uses the number of normal words found within a reference. Many subwords or tagwords can be associated with a single normal word, so this size variable inaccuracy will invalidate the statistic. 

Rating  This statistic has a range of 10.0 to +10.0. It quantifies the significance of the number of search hits in each reference. The rating statistic attempts to normalize the data by taking into account the size of the reference and the number of search hits found in it.

≈Actual/Expected  A bar chart comparing actual frequency (red) and expected frequency (green).  
Difference  Actual frequency minus Expected frequency.  
Total  The total number of words within the reference.  
%Actual  The percent of the total number of hits are found in each reference.  
≈%Expected  The relative size of the reference, or what percent of the total text is contained in each reference.  
%Difference  % Actual frequency minus % Expected frequency.  
% of total  The size of the reference relative to the size of the entire book. When you add up all of the percentages in this column, it should equal 100. Here, you can see that comedies are 29.562% of The Riverside Shakespeare.

The Rating Column
The Rating
column has a value between 10 and 10. If the rating is closer to 10, the actual frequency is much higher than its expected frequency. This formula is used to calculate the rating:
\[Rating = \sqrt{(ActualExpected)^2 \over Expected + 1}\]
This formula is similar to calculating a chisquare statistic for each cell in a table.
To avoid dividing by 0, a 1 is added to the Expected value.
Ratings greater than 10.0 are rounded down to 10.0.
Ratings less than 10.0 are rounded up to 10.0.
The expected values used in computing this rating are from Normal type words in the All Text (excluding any text from your notes).
Note: If you have filters on your search query, the expected frequency will be inaccurate.
