CHISQ.INV

The CHISQ.INV function in Google Sheets calculates the inverse of the left-tailed chi-squared distribution. It is a statistical tool that is used to find the value at which a specified percentage of the distribution is to the left.

Function Syntax and Parameters

Syntax: CHISQ.INV(probability, degrees_freedom)

Parameters:

• probability: The probability associated with the chi-squared distribution.
• degrees_freedom: The number of degrees of freedom.

Step-by-Step Tutorial

1. Using CHISQ.INV with probability and degrees of freedom:
   • Example: =CHISQ.INV(0.05, 10)
   • Result: Returns the inverse chi-squared value for a probability of 0.05 and degrees of freedom 10.

Use Cases and Scenarios

1. Hypothesis Testing: Determines the critical value for a given significance level and degrees of freedom.
2. Quality Control: Calculates the acceptance limits for a process based on a specified level of confidence and degrees of freedom.
