Concept of Critical Value with the help of Different Techniques to find it

A critical value is the test statistic’s value that establishes a confidence interval’s upper and lower boundaries. It explains how far away from the distribution’s mean you must be to account for a specific percentage of the overall variation in the data. For instance, 90%, 95%, and 99%. Your critical value will be the same …
