## Libraries.Compute.Statistics.Calculations.InterQuartileRange Documentation

This class calculates the mean of a particular DataFrameColumn.

Example Code

``````use Libraries.Compute.Statistics.DataFrame
use Libraries.Compute.Statistics.Calculations.InterQuartileRange

//Load a comma separated file
DataFrame frame
InterQuartileRange iqr
DataFrameColumn column = frame:GetColumn(0)
column:Calculate(iqr)
number result = iqr:GetInterQuartileRange()
output result
``````

## Actions Documentation

If the calculation otherwise has no primitive type, it sends it to the column as a raw object. Columns might use this if they have custom types.

#### Parameters

If the calculation returns true from IsIterable, this is an Integer object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the column.

#### Parameters

If the calculation returns true from IsIterable, this is a Boolean object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the column.

#### Parameters

If the calculation returns true from IsIterable, this is a Number object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the column.

#### Parameters

If the calculation returns true from IsIterable, this is a Text object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the column.

### Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

#### Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

``````Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
``````

### Empty()

This Calculation can be re-used if the Empty action is called before passing it to another column. Otherwise, it retains its data.

### End(Libraries.Compute.Statistics.DataFrameColumn column)

This action is called at the end of a calculation.

### Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

#### Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

``````use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
``````

### GetBottomMedian()

Returns the median in the bottom half of the column.

#### Return

number: the median in the bottom half

### GetHashCode()

This action gets the hash code for an object.

#### Return

integer: The integer hash code of the object.

Example

``````Object o
integer hash = o:GetHashCode()
``````

### GetInterQuartileRange()

Returns the interquartile range, which is the top median - the bottom median.

#### Return

number: the interquartile range.

### GetMaximum()

Returns the max value in the data set.

#### Return

number: the max value

### GetMedian()

Returns the median for the column.

#### Return

number: the median

### GetMinimum()

Returns the min value in the data set.

#### Return

number: the min value

### GetSize()

Returns the sample size for the column.

#### Return

integer: the sample size

### GetTopMedian()

Returns the median in the top half of the column.

#### Return

number: the median in the top half

boolean

### IsNumerical()

If this action returns true, the calculation is numerical, the column must be numerical If this is false, the calculation should be non-numerical, thus the column will not be required to be a numerical column action.

boolean:
