Show Your Love:

The Inverse T Distribution Calculator is a statistical tool used to determine the value of the inverse t-distribution for a given probability (p). It aids in estimating a specific value based on certain parameters, providing insights into the distribution of a dataset. The formula for the Inverse T Distribution Calculator is:

t_p = μ + t_{α/2, df} * (s / √n)

Where:

  • t_p: The value of the inverse t-distribution for the given probability (p).
  • μ: The population mean.
  • t_{α/2, df}: The critical t-value for the desired significance level (α/2) and degrees of freedom (df). This is typically obtained from statistical tables or calculators.
  • s: The sample standard deviation.
  • n: The sample size.

General Terms and Calculator

Here is a table of general terms commonly searched by users regarding the Inverse T Distribution Calculator, making it easier to understand without the need for individual calculations:

TermDescription
Population Mean (μ)The average value of the entire population.
Critical t-valueThe value obtained based on significance level and degrees of freedom.
Sample Std Dev (s)The measure of how spread out the data is in a sample.
Sample Size (n)The number of observations or data points in a sample.

Example of Inverse T Distribution Calculator

Let’s consider an example to illustrate the practical use of the Inverse T Distribution Calculator. Suppose we have a population mean (μ) of 50, a critical t-value of 2.021 for a significance level of 0.05, a sample standard deviation (s) of 5, and a sample size (n) of 100. Plugging these values into the formula:
