CHISQ.DIST

The CHISQ.DIST function in Google Sheets calculates the left-tailed chi-squared distribution, which is often used in hypothesis testing.

Parameters

• x: The value at which you want to evaluate the distribution.
• degrees_freedom: The number of degrees of freedom.
• cumulative: [Optional] A logical value that determines the form of the function. If cumulative is TRUE, CHISQ.DIST returns the cumulative distribution function; if cumulative is FALSE, CHISQ.DIST returns the probability density function.

Step-by-Step Tutorial

1. Using CHISQ.DIST with example values:
   • Example: =CHISQ.DIST(5, 3, TRUE)
   • Result: 0.2378

Use Cases and Scenarios

1. Hypothesis Testing: Calculate the chi-squared distribution for testing a hypothesis.
2. Quality Control: Evaluate the variability in a production process.
3. Social Sciences Research: Analyze survey data to test for associations between variables.
