T.DIST.2T

The T.DIST.2T function in Google Sheets is a statistical tool used to calculate the two-tailed Student distribution for a given value x. It is particularly useful in hypothesis testing and confidence interval calculations. Explore our comprehensive guide to understand its syntax and application.

Function Syntax and Parameters

Syntax: T.DIST.2T(x, degrees_freedom)

Parameters:

  • x: The value at which to evaluate the distribution.
  • degrees_freedom: The degrees of freedom for the distribution.

Step-by-Step Tutorial

  1. Calculating T.DIST.2T:
    • Example: =T.DIST.2T(2.5, 10)
    • Result: [insert calculated result]

Use Cases and Scenarios

  1. Hypothesis Testing: Determine the probability of obtaining a test statistic as extreme as the observed one.
  2. Confidence Intervals: Calculate the confidence interval for a population mean.

Related Functions
