Finding critical t-statistics using the probability distribution plot
The critical t-statistic can be found from either the Calc menu tools under Probability Distributions, or from the Graph menu and Probability Distribution Plot…. Here, we will find the critical t-statistic using the graphical tools used in probability distribution plots. In this recipe, we will find the critical t-statistic with 14 degrees of freedom for a two-sided test.
How to do it…
The following steps will show us how we can use the probability distribution plot tools to find the critical t-statistic:
- Go to the Graph menu and select Probability Distribution Plot….
- Choose the View Probability chart.
