NORMINV (Probability,Mean,StandardDeviation)


  • is the probability corresponding to the Normal Distribution.
  • is the Mean value.
  • is the Standard Deviation.

Description

  • This function gives the inverse of the Normal Cumulative Distribution for the particular Mean and Standard Deviation.
  • If , then .
  • using the iterating method to find the value of a Number.
  • Suppose the iteration has not converged after 100 searches, then the function gives the error result.
  • In , where is the corresponding probability of the Normal Distribution, is the Arithmetic Mean of the Normal Distribution and is the Standard Deviation of the Normal Distribution.
  • This function will return the result as error when
1.any one of the argument is non-numeric
2.Suppose  or 
3..
  • If and , NORMINV uses the Standard Normal Distribution.

Examples

  1. =NORMINV(0.01884908749,17.4,3.2) = 10.750011
  2. =NORMINV(0.998742,5.4,2.3) = 12.349244172
  3. =NORMINV(1,7.2,2.3) = NULL
