F.DIST

The F.DIST function in Google Sheets calculates the left-tailed F probability distribution (degree of diversity) for two data sets with a given input x. It is also known as the Fisher-Snedecor distribution or Snedecor's F distribution.

Function Syntax and Parameters

Syntax: F.DIST(x, degrees_freedom1, degrees_freedom2, cumulative)

Parameters:

• x: The value at which to evaluate the distribution.
• degrees_freedom1: The numerator degrees of freedom.
• degrees_freedom2: The denominator degrees of freedom.
• cumulative: [Optional] A logical value that determines the form of the function. If cumulative is TRUE, then F.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

Step-by-Step Tutorial

1. Using F.DIST with given values and degrees of freedom:

   • Example: =F.DIST(2, 4, 6, TRUE)
   • Result: 0.779193387

2. Using F.DIST with cell references and degrees of freedom:

   • Example: If A1 has the value 2, B1 has the value 4, C1 has the value 6, then =F.DIST(A1, B1, C1, TRUE) will return 0.779193387.

Use Cases and Scenarios

1. Statistical Analysis: Evaluate the F distribution for specific values and degrees of freedom.
2. Quality Assurance: Calculate the left-tailed F probability to determine the variability between samples.
3. Experimental Design: Assess the diversity of data sets in scientific experiments.
