PERCENTILE(ar,k)
- is the array of data .
- is the Percentile value.
is the array of data .
is the Percentile value.Description
- This function gives the k-th percentile value in a given range.
- Percentile means any of the 100 equal parts into which the range of the values of a set of data can be divided in order to show the distribution of those values.
- The percentile of a given value is determined by the percentage of the values that are smaller than that value.
- For example we can the 25th percentile is the value below which 25 percent of the observations may be found.
- The 25th percentile is called as the first quartile (Q1), the 50th percentile as the median quartile (Q2), and the 75th percentile as the third quartile (Q3).
- In general, percentiles and quartiles are specific types of quantiles.
- In is the array of data that indicating relative standing and is the Percentile value in the range 0...1(inclusive).
- This function will return the result as error when
is the array of data that indicating relative standing and 1. The array value is empty. 2. k is nonnumeric or k<0 or k>1.
