PERCENTRANK(ar,x)


  • is the array data and is the value


Description

  • This function gives the percentage rank of a value in a given set of numbers.
  • To calculate the relative standing of a data set we can use this function.
  • For example, a test score that is greater than or equal to 50% of the scores of people taking the test is said to be at the 50th percentile rank.
  • Percentile ranks are commonly used to clarify the interpretation of scores on standardized tests.
  • To find the percentile rank of a score is :<math>PR \%= \frac {L+( 0.5*S )}{N}

Where, L = Number of below rank, S = Number of same rank, N = Total numbers.

  • In PERCENTRANK(ar,x),ar is the array of numeric values and x is the value to find the rank. This function gives the result as error when array is empty .

where,

Array -  represents set of data.

X - represents the rank for value.

k - represents the number of significant digit for the returned percentage value.If omitted, it returns 3 digit after decimal point.


It returns the rank for data set as a percentage of the data set.

If k < 1, PERCENTRANK returns the #ERROR.


PERCENTRANK


Lets see an example in (Column2, Row1)

?UNIQ9722b96f1f2484ba-nowiki-00000004-QINU?

PERCENTRANK returns 0.66667.

Cosider an another example

?UNIQ9722b96f1f2484ba-nowiki-00000005-QINU?

It returns #ERROR(K=-1).
