The ERF.PRECISE function in Google Sheets computes the error function for a specified value, providing results that are essential for statistical calculations and analyses. It accurately returns the error function evaluated at a given point within a predefined range.

Syntax

ERF.PRECISE(x)

• x: A numeric value for which the error function is to be computed.

Example #1

ERF.PRECISE(1)

This function call calculates the error function at 1. The result, approximately 0.842701, indicates the area under the curve of a standard normal distribution from negative infinity to 1.

Example #2

ERF.PRECISE(-2)

Here, the function computes the error function at -2. The result, approximately -0.954499, reflects the cumulative probability for values less than -2 in a standard normal distribution.

Example #3

ERF.PRECISE(0)

This instance calculates the error function at 0. The result is 0, indicating that the area under the curve from negative infinity to 0 is zero, as it represents the midpoint of a standard normal distribution.

Error handling

• VALUE! This error occurs if the input is not a numeric value, indicating that the function requires a valid number to perform the calculation.
• NUM! Returned if the input value is outside of a predefined range in which the function can operate, suggesting a need for an input adjustment.

Conclusion

In summary, the ERF.PRECISE function in Google Sheets is a powerful tool for performing statistical analysis related to the error function. Its ability to handle a variety of numeric inputs while providing precise results is invaluable for researchers, statisticians, and data analysts alike.
