sc
A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.
Calculates the second percentile of the series's elements YValues.

# Syntax

Visual Basic (Declaration)
```Public Overloads Shared Function Percentile50( _
ByVal sc As SeriesCollection _
) As Series```
Visual Basic (Usage)Copy Code
``````Dim sc As SeriesCollection
Dim value As Series

value = StatisticalEngine.Percentile50(sc)``````
C#
```public static Series Percentile50(
SeriesCollection sc
)```

#### Parameters

sc
A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.

# Remarks

Recall that the percentile is the value such that at least `interest`-percent of the data set items are less than or equal to this value, or equivalently if at least `(100-interest)` percent of the items are greater than or equal to this value.

Remarks:

1. The `50`-th percentile is the measure of centrality of a data set known as the median. The median can also be evaluated using FinancialMedian.
2. The `25`-th, `50`-th, `75`-th percentiles are often referred to as the `1`-st, `2`-nd (median) and `3`-rd quartile respectively. The term quartile refers to the fact that these three values will roughly divide the data set considered into four equal parts.
