The Statistic Box shows several statistical figures calculated automatically from the indicator values of all feature in the report.  It is not visible by default – you must insert it using the ‘Insert’ menu (see image in section ‘Insert’).

If a filter is applied, the statistics will be calculated on-the-fly for just the filtered features. This works for a filter applied through the Filter Explorer and for geographic filters which can be applied by selecting a subset of the map features and then clicking the Filter button int he map toolbar.

The default statistics are the following:

Variables	Description	Formula
count	The number of features	–
sum	The sum of the indicator values
mean	The arithmetic mean of the indicator values
median	The numeric value separating the higher half of the indicator values from the lower half.
min	The smallest indicator value	–
max	The largest indicator value	–
range	The difference between the minimum and maximum values
lower quartile	The 25th percentile.  If the rank is not integer, the ‘Linear Interpolation Between Closest Ranks’ method is used.	with
upper quartile	The 75th percentile.  If the rank  is not integer, the ‘Linear Interpolation Between Closest Ranks’ method is used.	with
interquartile range	The difference between the upper and lower quartiles
variance	A measure of the average distance between each of a set of data points and their mean value; equal to the sum of the squares of the deviation from the mean value.
standard deviation	The square root of the variance in the units of variable

The property ‘Text’ of the Statistic Component in the config.xml file allows you to amend the displayed statistical figures. By default the value of this property is:

 count: ${count} <br/> 
 sum: ${sum} <br/>
 mean: ${mean} <br/>
 median: ${median} <br/><br/>
 min: ${minValue} <br/>
 max: ${maxValue} <br/>
 range: ${range} <br/><br/>
 lower quartile: ${lowerQuartile} <br/>
 upper quartile: ${upperQuartile} <br/>
 interquartile range: ${interquartileRange} <br/><br/>
 variance: ${variance} <br/>
 standard deviation: ${standardDeviation}

The substitution variables, which hold the actual values, start with a dollar symbol and are enclosed in curly brackets like this: ${…}. You can amend this text as you wish, for example by adding further static text or basic HTML commands (e.g. <b>…</b> would let the text between appear bold).
