calculateBoxAndWhiskerStatistics

public BoxAndWhiskerItem calculateBoxAndWhiskerStatistics(List<Float> values)

Creates a box-and-whisker data holder for the given list of values. The data holder will be populated with the median and the 5th, 25th, 75th and 95th percentile values as follows:

• median = BAWI.getMedian()
• 5th percentile = BAWI.getMinRegularValue()
• 25th percentile = BAWI.getQ1()
• 75th percentile = BAWI.getQ3()
• 95th percentile = BAWI.getMaxRegularValue()

The mean and outlier values are currently not calculated (may change in the future).

Parameters:

values - The list of values which must be sorted in ascending order

Returns:

A BoxAndWhiskerItem object

getPercentile

public float getPercentile(List<? extends Number> values,
                           int percentile)

Calculates the percentile values from a sorted list of values. If the percentile falls between two elements in the list the average of the two nearest elements are used.

Parameters:

values - The values which must be sorted

percentile - The percentile, a value between 0 and 100

Returns:

The percentile value, or Float.NaN if it could not be calculated
